Came across this thread by accident; thought I'd comment.
From the aforementioned mods I have played the following on BG2:EE on Linux. (I had to patch some of them to make them work with EE.)
Check the Bodies -- 1-4 / 1-5 / 4
Very much a mixed bag. The main component adds a bunch of unrelated areas and encounters - and some of them are great fun, while others are a complete waste of time.
Also, I couldn't get the separate "Candlekeep flashback" component to work on EE, so I only installed the main component.
Even the components that are fun, are poorly balanced though (i.e. give overpowered loot, for example drow equipment in chapter 2 that won't disintegrate until you visit the underdark exit map in chapter 6).
Colours of Infinity -- 5 / 4.5 / 4
"The White Queen" and "Tales of the Deep Gardens" are excellent. "Innershade" is fine as well though I found it a little less fun than the other two.
The loot you get is also pretty well balanced for chapter 2 parties.
I encountered some very minor bugs, like some items showing their full description even before I identified them, and my party facing "the wrong direction" after stepping through some doors.
Tower of Deception -- 4 / 4 / 5
A small run-of-the-mill linear adventure. Not particularly exciting, but well put together.
Assassinations -- 5 / 4 / 5
A neat quest-line for evil parties (or neutral ones, if you're good at rationalizing ).
I loved that it took me to various nooks and crannies of the outdoors Athkatla district maps that I had never visited before in my BG2 playthroughs.
Planar Sphere Mod -- 4 / 5 / 4
So much fun... if you're a powergamer.
If you're someone who takes game balance, role-playing, or Forgotten Realms canon very seriously, then stay far away from this mod. Otherwise, give it a try!
Everything goes to 11 in this mod: The encounter difficulty, the over-poweredness of the loot, the XP rewards, the sheer megalomania of the plot. All of it totally out of control. And that's what makes it so fun...
Do not attempt it until you have have a high-level post-Watchers Keep chapter 6 party, because I'm not kidding about the encounter difficulty. Imagine having to fight Demogorgon and the Twisted Rune at the same time with SCS installed - that's about the level of a standard battle of this mod. Liches are not bosses in this mod, they come in groups as minions of a boss. That kind of thing.
PS: After completing it, I had to throw away the most epic loot items and use the cheat console to remove 1 million XP from each character again - because otherwise the rest of BG2 and ToB would have been no challenge at all anymore.
