I voted reform in the last election. My reasons are pretty much as you have said.
The country is too full with too little resources now. With our youngsters unemployed we should not be bringing in more people. We have plenty. Train our youngsters please and stop all this immigration (legal or illegal). No other party seems to be prepared to say it's a problem except reform and now restore.
NHS needs reformed. Perhaps can we keep it in some form and make it co-pay but nobody except NF seems to be prepared to say the NHS is a mess and needs changed. So I can't get a GP appointment and I've been waiting now for 15 months on a waiting list for treatment they say I need. Neither of these situations screams the NHS is doing a great job. I think we should keep it for basics but make the rest of it private or co-pay. Unfortunately all the politicians seem scared to broach the NHS so NF is getting votes on this subject too purely for saying yes it is needing changed.
The whole welfare thing is just a joke now. Working people being taxed and welfare claimants being rewarded. So yes we do need someone who is prepared to make hard choices. Only reform or restore seem to be prepared to make these tough choices. So again they get my vote. The triple lock needs to be changed but my main bug bear is all these unemployment/disabled benefits and I use the word 'disabled' loosely because we know what a joke that has turned into (apologies to the real disabled people out there)
I don't agree with all their policies but we just cannot continue with this labour nightmare of raise taxes (killing growth), keep shelling out tons of money (thus borrowing more which we can't afford). We need jobs, growth, change, hard decisions. AB is already showing signs of trying to keep everyone happy so I don't think he is going to turn it around unfortunately.
I don't care if NF is rich with a ton of houses. To me that says he understands business, economics. I care that he is willing to make tough choices to stop the decline of Britain. Pretty much every PM we ever had was a rich, privately educated person. Not sure why NF gets such a hard time about it. He is no different to the rest in that respect. I don't particularly like NF but I don't have to. If he makes change, brings growth, changes public services not working, stops immigration then I will vote for him. (Actually I'm probably going to vote restore when they have candidates to vote for but that's another subject and yes again I don't like some of their policies either).
I want to like Kemi because I was traditionally a tory voter but I honestly think she is all talk and does not inspire confidence. I might be wrong about her but that is how I feel just now and so no I wouldn't vote tory with her in charge.
To a degree reform (or restore) is a protest vote against the killing of the UK's financial viability by labour.
