Not a lot of real advice on 'new' tools, as I don't have many; but here's my experience.
I have both the barrel and top handle Bosch - both older versions I picked up used. I love both of them but prefer top handle in general - even though hands are 'normal' sized, neither small nor large. One has the long screw driver blade change, bit of a PITA, but you won't find that in anything new.
In a bundle of inexpensive (a sale of recon) Ryobi cordless tools, I bought a One+ (18V) jigsaw that handles really well. I have only used on deck work, but in general it felt as powerful and 'accurate' as my corded Bosch tools. I was actually impressed - of the whole Ryobi set I purchased, this and the impact driver are the best of the bunch (circ saw, recip saw, hammer drill, impact driver, and jigsaw). It is not a premium model by any means (it's a Ryobi) but I guess any decent jigsaw with a blade support/guide (that little bearing/roller just above the surface) will meet my needs. I rarely make 'a critical cut' with a jigsaw.
I would like to win the lottery and get a Festool if they handle dust (chip) collection. Getting a stream of wood chips in my face is my least favorite part of using a jigsaw; gotta position your face just right to get this spray of chips, but for some reason that often seems to be my best view of the cut! Good reminder to wear glasses.
