I used low temperature solder Sn42 Bi58 then soldering a few small packages by hand. Maybe it does not make a big different but it work.

Usually I chose simple to solder chips unless there is a good reason to chose others, availability is usually the reason I have to use harder to solder components. Read something about check quality of these packages with pads underneath is no easy task even for these with professional equipment but are no sure. I would however expect a slightly less problem and hence slightly lower price as well some less quality problems if chips are simple to solder but probably no big difference though my experience i very limited.
