Can't remember which offhand, but the longer-handled Felcos – gives you a bit more leverage if you need it (or a bit easier on yer elbow if you've got tennis elbow..)
Whatever you get, it's handy if it allows the pivot to be tightened – I've a pair of Wilkinson Sword jobbies (and they weren't cheap ones) where the nut's held on position by 4 counterpunched spots…nope, they don't hold 🙁
It's not very helpful, but my other favourites are a) a pair I found in the garden at our previous house, pretty much buried (and I suspect I may have recently done likewise with 'em) b) the pair my parents bought, probably in the 50s – still work a treat.
