I'd say if you've got a ratchet strap, a rubber mallet and some dish soap, changing the lolipops is easier... no ball joints to piss around with!
granted, as you've got new wishbones, you don't need to worry about keeping the old balljoints in tact, but even still, they can be an arse to separate sometimes.
If it helps, I got my ratchet strap from the shelf at B&Q for £7. 25mm wide, 5m long... perfect for the job
however, if you're changing the wishbone, then it will undoubtedly be easier to mount the lolipops to the new bones outside of the car...
