It takes time to become acquainted with sleeping in a one person tent if you are used to 2+ people tents. I have two kits, light weight using a Notch Li, and a medium weight for winter/ bad weather trips. In the Notch, I basically have enough room to switch positions on my pad and sit up. there's no sideways room. It took me about 10 or so trips using the notch for the smaller space not to bother me. I do not hang out in it, unless it's pouring, using it only for sleep. I do not cook in or near the tent, that's just asking for trouble at some point.

I cook in my tent in bad weather! Half my body is in the tent, the other half is hanging out. It works!
The primary design difference is that the Copper Spur is 100% free standing with the poles shaped like a pair of 'Y's attached at the legs.
The Tiger Wall requires the corners (at the feet) to be staked out because the pole design is a single "Y" with a stretched leg.
Otherwise, if you look at the specs, the Copper Spur is slightly larger in square footage (both inside and the vestibules).
Naturally, the Tiger wall packs a little smaller and lighter.
When I did the JMT with my BS Copper Spur UL2, I was able to bring EVERYTHING (except the bear canister) into the tent at night.
I had read reports that occasionally people would have their boot laces, hiking pole hand grips, of other gear attacked by critters, so I didn't want to leave anything outside. So I had my back pack, hiking poles, and all my gear in the tent. I used a sitting pad that I would turn "dirty" side up and sit the hiking boots on it.
I'm a pryamid tent convert and into extreme multitasking. Gatewood Cape, Serenity NetTent, 1.5mil Polycryo Footprint, 6 Ti stakes all pack easily into a S2S XS 2.5L stuff stack and weighs 25oz - that's about 60% the bulk and weight of my equiv. BA FC UL2 for ~same total floor area.
Mids are modular, so while I like sleeping inside the bathtub floored inner tent (creepy crawly fears while obliviously asleep), I usually collapse it into a corner (3clips, 20sec) while awake for more interior room, not having to zip though doors, and able to leave my shoes on 'inside'. If it's not too windy, I can also raise the pitch height to create more interior room. The fly alone is amazingly effective against flying bugs playing against their own instincts (to avoid enclosed entrapments, and to seek escape out the large 'skylight' when they feel trapped).
With the inner solo tent collapsed, I can fold the footprint to size to create a giant floorless vestibule to cook in, use my camp chair (Litesmith Qwikback), and have a 2 person sized interior to move around, change clothes, fiddle with gear. In nasty weather, I pre-dig a indoor latrine in the unused corner opposite the door (pee while lying on side, then layer dirt on top) which also works for those middle of the night pees (drop inner tent with 1 peak clip), and in the morning if it's still pouring, I can make breakfast, pack everything up, and even take my morning #2 dump** in another cathole, all while inside under the protection of the fly. ** note: last step before moving on, and wild camping only - not at an establish campsites.
FWIW, I can even use the fly as sit-down shower stall in chilly weather (to block windchill and in direct sunlight, to add 'greenhouse' warmth). It's also a rain poncho and, for me, a critical winter daytrip EDC as a: full/3qtr 'bothy bag', Palmer furnace, and emergency puffy mid-layer.
So if necessary, I can do everything I need from inside my tent. As far as killing time while stuck inside a tent (due to rain/cold/wind/bugs/long nights/stealth camping) - it's basically sitting cross-legged on a pad to do things with my hands (cook, fiddle w/gear, play mini card/dice games), or sit in chair/lie on pad to relax and play with my smartphone (listen to music, watch a movie, read ebooks, surf assuming reception, etc).
