So the price is one thing. Granted my personal projects are only just me but some of the projects I've collaborated on before involved multiple people so just for simplicity's sake I moved all of them over (I hate having multiple services for the same type of thing; GitHub is the only exception because their private pricing is really high and it's really difficult to do OpenSource anywhere else).
I'm not going to lie and this is going to sound kinda shallow but I thought GitLab looked nicer too. Granted this wasn't the main thing that made me move but it did help nudge me a little.
Beyond that it's not like git is very different between places so it's kinda hard to differentiate in my opinion.
