My List of ENB (Skyrim

Skyrim LE

2. I Have A Fever (сolourful ♥) (I use it with "Rebalance_Light.esp", "Rebalance_Light.bsa", "EnhancedLightsandFX.esp" and "EnhancedLightsandFX.bsa" files from Rebalance Light v2.8.5)

3. HRK (sweet and cozy fantasy, for light-skinned characters predominantly)

4. Anko (for light-skinned characters, very performance ENB)

5. Suki's Preset (realistic scenery / landscape / environment)

6. Bleak / Unbleak (the cold of the North, for characters)

7. Poupouri (First Seed) (for characters, immersion, cozy)

8. Snapdragon (for wivid, colourful portraits, but not for playing)

9. The Grim and Somber (immersion, cozy)

. . .

I also advise use MeonMeon's LUT for Anko and Snapdragon Prime ENB. How to add LUT to any ENB.
And here are some useful tips for setting up the ENB.

Oblivion

1. Glow Hell (very colorful ♥)

2. Glow Hell + My Enbpalette (for screenshots-portraits (or for landscape screenshots, if you know how to tweak the ENB settings for a specific moment))

3. A Tweaked (colorful, warm)

4. SirArsty (Moderately colourful. Skip "ATE" step.)

5. Monkey (for environment: scenery, landscape)

6. Cinematic ENB for Oblivion - New Dimension (The initial moderately colourful, dark and grim version of this ENB, which is removed from everywhere. Not the version from Nexus!!)

7. Cyrodiil (warm and boring)

Skyrim SE/AE

1. PI-CHO v7.5 for Obsidian Weathers (not ideal but very good)

2. Berserkyr (best realistic)

3. Rudy for Cathedral Weathers (warm character skin color in interiors, but bad SSS in exteriors)

4. FN (realistic)
