The best one is the one you find most, intuitive, yes.
You need some automated way of managing references for a taught masters, in my view, for a couple of reasons.
Firstly, because at masters level, independent reading is expected. It's not enough just to use the reading list, so you'll need some way of tracking your additional sources.
Also, you're likely to be time pressured at some points as assignments become due. RM software is much faster than manual referencing. You don’t want to be spending hours typing out references when you've got another couple of pieces of work due, or losing marks because you submitted incompletely referenced work because you ran out of time.
It's also really easy otherwise to lose a key reference that you're hanging an argument on and not be able to find it again. At least if it's saved into your RMS and appropriately annotated you have a fighting chance of tracking it down.
And finally, correct referencing is part of demonstrating academic integrity. Increasingly, students are using generative AI, like chatgpt, to cheat. One of the things it does is to hallucinate/ make up fake references. So as an arse covering exercise, you need to make sure your references are correct. It's much easier to do that with an automated system that transfers the data into your documents than typing it in manually and risking transposing page numbers, or misspelling author names, and having the reference flagged as fake.
Genuinely, reference management software is not that hard to use once you've done it a couple of times. My advice would be to hit the ground running and start using it straight away. You don't want to be couple of months in with assignments due and then have to input 8 weeks worth of reading at once.
