Korean dramas, Japanese dramas or Taiwanese dramas?

Question:

so im into kpop and everything in east asia from clothes to food!!!!
i recently got into east Asian dramas and iv watched at least one drama from each category (Korean, Japanese and Taiwanese). i also searched up some dramas i could watch and it seems like i have a lot of catching up to do!! :P
so pretty much, i want to start with one category and i seem to be very picky because i notice specific things that would upset me about a drama. for example: its too slow or the actors are to cheesy or something. (i know it doesn't apply to all of them)
im into a good, solid story line with great acting. (and i really hate when it gets cheesy!!!)
i just want some opinions on which category i should start with and why. And if you could give it to me in pro and con opinion that would be even better!!! for ex: korean dramas - pros: very good looking actors cons: sometimes the story is rushed!!!

im only asking this because i haven't watched enough from each category to say anything.

i know that every story is different regardless of the category but most of the times, its generally the same!! and eventually ill watch a bunch of dramas from all categories!! i just need somewhere to start!!!!

Answer:

For what i had watched recently and would like to recommend to you:

For the Korean drama, you can watch the most recent one like Heart String and City Hunter.

For Taiwan drama, Drunken to Love You and Sunshine Angel.

For Japanese drama, Hanazakari no Kimitachi e 2011
