Better Cities/City enhancing mods/Unique Landscapes Compilation/The Hesu Mod Collection
Big city mods or mods like Unique Landscapes and HESU are going to lower the stability and FPS of your game. Oblivion's engine is simply incapable of handling these types of mods well. Better Cities in particular can also be imbalanced concerning gameplay. These mods tend to have compatibility problems as well.
Kvatch Rebuilt
It's still a work-in-progress even today. Voice acting is regarded to be quite lacking in quality, and a lot of the mod content is unrelated to rebuilding a city. Though I never completed it, I recently watched a YouTuber play this mod and they encountered a very painful looking underwater maze that resulted in them getting quite aggravated, and they had to use the console to get through it. That's personally not my kind of thing.
Knights of the Nine Revelation
It's not that bad, but I wouldn't give it another go. Mostly OK voice acting (to be expected, being from 2012), with some quests involving vanilla dungeons that have been extended by the mod. You will be revisiting at least one dungeon you've already been through.

You need to make sure you bring a certain item when being sent to a dungeon (apparently a character hints at it but I didn't see it) or else when you get to the end of the dungeon, you won't be able to progress, and will need to leave and return with the item in question.

At least one quest had no choice regarding dialogue options, i.e. I wasn't allowed to decline helping someone who asked for assistance. This may be expecting too much from a quest mod however, especially one revolving around holy knights.

There were few FPS intensive areas where I got down to the 20s and even 10s. I would have appreciated more quest markers personally, instead of vague journal entries.

One NPC was straight up naked for seemingly no reason, until I attacked her. I got no reaction from the NPCs around me when I murdered her (this was in a new location added by the mod).

A fairly annoying deep underwater object collection quest also exists in this mod, which most people will not like. I had to use the console to complete this section due to not being able to find enough items for the quest (there also was a giant crystal here with no collision).

Another part I did not like was a very silly event, where you must constantly punch and kill an enemy that morphs into your foes three different times, while you are naked. This get tedious fast, depending on how low your Hand to Hand skill is (likely 5 for most people).

I encountered a problem where I freed some slaves and half weren't leaving their cages, despite being set free.

You better hope you chose the right path options in this mod or found the correct item, which can hidden fairly well and not forced on you, otherwise you won't be able to finish the questline.
Oblivion Uncut
I've simply heard too many reports of problems like bugs or crashes with this mod. It is also a big problem compatibility wise with other mods.

Clean Up Cleaned Up/Clean up
Can break MOO dynamically placed items, by cleaning them up undesirably, and outposts. Can break companions by cleaning up AI tokens from them. Also may clean up horseshoes from Ultimate Leveling.
