This is true @waitingquietly but for a solicitor apprenticeship (definitely be sure you want to be a solicitor as there aren't really barrister apprenticeships yet) and all degree apprenticeships at the end you are at the level of finishing a grad scheme. So, for example, 6 years solicitor apprenticeships, in the 4th year they do the SQE, in 5th and 6th year they do training contact so 4 x 6 month rotations. Year 1-4 tends to be 1 year in each team/rotation. So you can not compare a student finishing a law degree to the end of a degree apprenticeship because that's not a fair assessment. The 4th,5th, and 6th year are the same for them in terms of the plan. You can compare a uni student finishing a 3 year law degree to a degree apprentice finishing their 3rd year of apprenticeship and having work experience.
But a degree apprenticeship in law means you only do the 7 compulsory modules which make an LLB degree, this is what is done in 1st and thw majority 2nd year in degree, so you have no optional Y1 modules and then more in Y2 and then Y3 is open to anything plus dissertation. So law school means you can explore more areas of law, not just the compulsor
y 7, so family law, sports, media/entertainment law, immigration law, human rights. Often with a solicitor apprenticeship, you are going into commerical/corporate (though this has many factions, mergers, real estate, pensions etc), or criminal (less of these), or maybe family (again quite rare).
So if you want to do other areas of law or aren't at all sure what area, a law degree is probably better. You can do vacation schemes, internships, mini pupillages etc across the way to get experience - and when applying for a training contract or a pupillage, they aren't going to be unfair and think you need a ton of work experience because they aren't comparing you to their 3rd year apprentices, so they won't have the same expectations of experience. You'll have more theoretical knowledge that apprentices may not have, and they'll have experience with clients, understanding things you learn on the job, etc.
That is why by the time of a training contact and the last 2 years of a solicitor apprenticeship, you are on the same pay, doing the same things, etc, at the same point. During Y4 the only difference is the apprentices are doing the SQE and working but often get more study time/leave as it is very taxing, I know many firms give them 2 days 'off' when in Y1-Y3 they only have 1 day off.
There are pros and cons to both, and it's often done to each person as well. There are opportunities univeristy offers that you won't have on an apprenticeship (internships in many areas, research, roles like academic rep, running societies, doing outreach projects, trips, study abroad, being an SU councillor perhaps, also doing pro bono Law clinics). The same way a solicitor apprenticeship offers things like that day-to-day experience, being paid, etc. It's often very dependant on the person; are they sure they want to do that area of law for minimum 6 years, before perhaps needing to do extra courses do go into a different area of law.
They will have done the compulsory 7 that a degree has to get an LLB but when looking to go from corporate law to criminal, they have only done the criminal law module which by the end of their apprenticeship is 4ish years ago (and some during the SQE, so 2 years ago) so they are on the same level of a grad finishing their 4th year SOE looking for a TC in criminal law firm in terms of lack of experience and pratical knowledge when applying. It's also even harder if they wanted to go into a part of law where they didn't do it as a module in their degree because they only did the compulsory 7. So they may need to do further courses etc.
So if you aren't sure what area of law you want to do, whether you want to be a solicitor or barrister, want to do work experience and internships in different industries, a law degree is probably better, and if it was the opposite a degree apprenticeship is probably better.
That's why a lot of firms are saying that during the TC and last 2 years of the apprenticeship, and after when people qualify, they are noticing great benefit in how both apprentices and law degree student work together and they learn a lot from each other because they are both 'missing things' e.g experience, understanding clients, the way the office works, pratical implementation of the law, or knowing more theory/case law, opportunities of student leadership, outreach work, talks, research etc. They have being saying how much it helps both of them whatever route they've done.
