I think Arachnophobia is better in my opinion.
The control that Arach. brings to the set can not be brushed away. People and certain characters love to be mid screen, full screen to do whatever. Arach. can 100% control that. The air? Arach. 100% controls that. Now you have your opponent questioning their basic mobility, that's strong. Sub zeros are USE to getting knocked away with 121 and doing free, ice shards, whatever it is, not against Arach. you arent. Scorpion LOL watch him duck full screen for 20 min.
I've been using arach to hold neutral big time. Bug spam is nonstop from me then I read the jumps or strings whiffs with her teleport and so it goes.

Buzzed is fun, no question. Lot's of crazy shit that you can setup and get rolling. However, what I think are downsides is, sometimes you set something up and if they don't fall for it you might have to settle for a hard knockdown. There is no question about it the game favors STRONGLY the person being knocked down. I don't like that idea. (they literally have about 8 options on knock down) Buzzed is one of those things that when it works, it works well. When it doesn't, I question why I give up damage for this variation etc. People throwing fireballs nonstop full screen (half the cast or more has this) na, I'm good. I'll keep the teleport and keep the mind game goin with them.
(I also know that buzzed can be setup to handle most wakeup options however, that's just ONE setup of her many in that variation so....................)
