Based on wot I own:
If you're on a budget - TGI Extreme. Can't buy a better quality gigbag for the money.
If you have loads of stuff - Gator Pro Go. I got all my cables, power supply, IEM setup, batteries etc in the main pocket, a 10" tablet in the dedcated inner pocket and my Fishman preamp in the top compartment.
If you want a super premium but slim gigbag - TGI Ultimate. Not just an upmarket version of the Extreme, it's a superb gigbag and rock solid.
I also have a Gator Pro Go X (now renamed to Transit) which is also good, possibly a little bit nicer than the TGI Extreme but unless you get it in a serious sale it isn't great VFM in comparison.
It's pot luck what you get I think, a lot of shops still have older stock. I recently got another Extreme for my Parlour bass (classical guitar model) and it has the solid handle, was from Absolute Music despite them advertising the new one on their website and eBay store with stock pics. Agree it's nicer than the two piece version so might be worth asking.
