Good luck with your research and decision-making.
I hope any possible pump application goes well. I am another pump convert after many years of ‘pump aversion’.
I think one was first suggested to me 5-6 years before I finally took the plunge - and I had all the same questions as you do and more besides!
What convinced me to give it a go were the experiences of pump users (including some blog and forum posts)... and also that I could try it and then switch back if it wasn’t for me. As others have said, it does take work... I has some early ‘wins’, but I think it was 6-12 months before I really felt I was getting the hang of it.
I know very few people who have switched back... but there are some for whom pumps just don’t work out in the end. So give it a good go, expect a few frustrations and ehhhhhhh? moments... but ulrimatelymI would be amazed of you both don’t end up loving it.
