It just depends on a lot of things. First, what your own standards are. For example, it seems a lot of trans people want someone who accepts them as trans but not someone who actively tries to date trans people, that'll conflict and narrow your pool significantly. Some place a restriction on race, some on gender, some on income, some on looks, some on age, some on certain aspects of personality, etc. Not saying any of it is wrong; because it isn't. But people with a broader pool will have an easier time finding someone. (though if they're just lowering their personal standards out of desperation they're not going to be happy, also some will try to broaden their pool by staying stealth for a long time to their partners, that's a terrible idea)
In general, I believe older trans people will have an especially harder time than younger trans people, pre-ops will have a harder time than post-ops, passable trans people will have an easier time than those who don't, and, I believe, straight mtf's have it harder than ftm's or mtf lesbians.
But remember, the internet is a wonderful tool.
