me and lines:
i've discovered that the lined vs. unlined is really a thing on TB but not so in the real, non-binary, actual world. i went from sax to DB to EB in the mid 70s --- fretless EBs were unlined (where i lived!). so i've always played unlined --- why introduce lines to a cat who doesn't know from lines?
(and i don't play fretted instruments, so: lines are 'out of context' for this player.)
me/you and glarrys:
i've purchased several glarrys to use just the bodies (lightweight, nice looking paulownia) and to mount my own fretless necks/hardware/electronics/etc. they have worked brilliantly for making lightweight instruments (yay!). as for the playability:
- if you don't know what an instrument might need to be perfect for you = do not buy these!
- if you know, but can't do the work yourself = there will be an expense to have others do the work.
- if you need to compare out-of-the-box playability to a 2K instrument = these aren't your huckleberry...they'll need work!
- if you have the time/interest/skills to bring wood/metal parts to playable perfection = these are great deals!
- if "resale" is your favorite rationalization = no "price point" will deliver!

stay away...or get out of the way!
TL;DR, per the OP: i really like the glarrys for parts! i purchased the fretless because i was curious, but i already had an idea for a P-bass with a maple neck. a glarry-type ax affords the tinkerer/modder a great platform for cheap. if you can't set up your own instruments = don't do it! if you can, and if you like chunky necks, these glarry fretlesses might be all you ever need!
i'll post these again, for reference (my modded, perfect, 6.2 lbs, glarry P):
