The following tags will be rated by how well they work on Illustrious.
Wamudraws: ★★☆☆☆
Isn't very noticable. It seems less like Wamudraws and more like a general "chalk" style with the only resemblance being the eyes; even then, you need to put the strength at 1.5 and say your prayers if you're trying to generate a specific character.
-

Khyle.: ★★★★☆
Amazing tag that shows up very well. Leans a bit too much into warm colors, which messes with a character's appearance. Very dynamic, expressive, and adds a good touch to any generation when watered down.
-

Inkerton-Kun: ★★★☆☆
Aside from the white-pinkish colors and maybe the eyes, this style doesn't show up very well with LoRAs. Increase the strength if you must.
-

Raion (Raionart): ★★★☆☆
Artist is primarily known for drawing DDLC characters, which consequently means a lack of diverse data, which means certain characters won't look how they're supposed to. Very situational tag, but does show up without strength play. You can tell it's doing what it's supposed to because of the Patreon watermark and the bloom effect.
-

Alex Ahad: ★★★★★
Does exactly what it's supposed to without compromising too much of the character you wish to put in the style, no strength adjustments required. Perfect tag.
-

Bacun: ★★★★★
Artstyle is very recognizable, no strength play needed. Perfect tag.
-

Porforever: ★★★★☆
Unique and cute artstyle, but it does not work with everything. Locks characters in a pseudo-chibi style no matter what you prompt. Water down if you're trying to generate MILFs or something.
-

Metata: ★★★★☆
Unique, visible artist, but expressions can be a bit lacking.
-

Colo (Nagrolaz): ★★★☆☆
Like Raion and Inkerton, doesn't show up very well if you're trying to prompt a character LoRA or whatnot. Strength play may be a requirement.
-

Rariatto (Ganguri): ★★★★☆
Good for a refreshing look. Art style might be a bit too strong, which will mess with specific characters.
-

Ilya Kuvshinov: ★★★★★
Very visible and recognizable artstyle. You'd think this would have the same problem as Khyle where the purple tint would overpower everything else, but I surprisingly haven't ran into that issue yet. Perfect tag.

Noill: ★☆☆☆☆
It's only Noill in name. I have no idea whose art style this is, but it's definitely not his.
-

Luxu: ★★★☆☆
Noticable artstyle, artist is more known for NSFW things but otherwise doesn't add much. Strength play might be required.
