Haven ridden suburban express about 3(?) different round trips, I'll have to say I'll be giving my business to Peoria Express instead. While personally I haven't had too many problems to SubEx (besides a late bus), seeing the way the owner retaliates against yelpers, threaten students with lawsuits, and the general attitude towards passengers that subex has (ie: passenger shaming page on their website), turns me away from supporting such a business.
Besides, PE allows small pets that fit under the seat and SubEx doesn't -shrug-
