Agreed on every point. We've never gotten ABS, or nylon, to work reliably. The "experts" say you need a heated bed (which our Lulzbot Mini has) but also the enclosure you mention and stable ambient temperatures plus some sort of special voodoo chant to keep the ABS deities placated... it just wasn't worth it, we gave away all our spools of ABS.
Nylon has its own set of challenges, one of the biggest being that it's very hydrophilic so you're constantly heating it to get rid of moisture (yes, we kept it in sealed bags with dessicant). We also could never find the magic recipe that gave us both minimal stringiness AND good interlayer adhesion at the same time, since they have competing temperature requirements.
We've settled on PLA for most things, and it's remarkably broad in its applicability. We use PETG rarely, and flexible filament when necessary. But our go-to solution is PLA.
YMMV, just my $0.02, worth only what you paid for it, etc.

We use about 10 FlashForge Finders at work printing PETG 24/7, just put some glue stick on the bed and it’s good to go. The printers have more than 2000 hours each printing PETG with next to no failure rate so I don’t think it will be a problem.
BTW; PET/PETG/XT is a great material to print with, its strong and slightly flexy so it won’t shatter like PLA, gives a good finish to it and best of all its easier to print than ABS. Id recommend printing with it if you want something stronger than PLA.
Also you won’t damage your printer if you print ABS; the hot ends at work have printed thousands of hours with temps of 240 degrees C and never burnt.
