Choose whichever suits you best, I'm using yannou's cwm recovery (the one that came with rooting tutorial), mainly because, it never gave me any issues, also because I don't need more features, but the biggest reasoon, is just that I'm really lazy.
And there aren't many recoveries, working for pico
1. Cwm(yannou's)- which is basic, don't have many features, has everything that I need
2. TWRP- it's touch recovery, it has more features than cwm
3. Phill's- This one looks really, really good, also has a lot of features, it's main advantage is that it supports backups from twrp, and also from cwm.
That's it, choose whatever suits you best.
