U2000
If you may, it sounds like you are running away out of fear to losing to someone within your rating. Does a loss against an expert feel significantly less bad to a loss against a 1900?
If you want to be a master you have to beat u2000 consistently. It's better to deal with the problem now rather than later

Answer depends on how you are feeling.
if you study enough and have confidence go 2200 and attack. keep in mind that the feeling of if having much better position but shaky play and losing advantage is painfull.
if you dont feel stable enough but shaky; afraid of losing; or you want to build confidence in yourself and stability go u2000 or u1900.
I often like to play lower rated than me, becouse i have holes in my game that winning positionally vs lower or equal rated often feels better than winning vs stronger opp who did a blunder or underrated you.
as someone typed you have to be able to beat 8/10 those bellow you, can you. can you hold a draw in sleighty worst position vs lower rated? do you have good technique with bishops knights in unballanced endings, all this will matter more and more when u go up in rating,
