In my opinion, '感到' emphasizes the person who is speaking, but what feeling that comes to him is not so important. In other words, this phrase is more subjective. In addition, it's not a noun while '感觉' can be used as a noun. <>能和你见面,我感到很荣幸. <>在这种地方,我感到压抑. '感觉', is a verb as well a noun. It puts more importance to the feelings that somebody has in mind. And it can carry an abstract mood in words. <>你现在是什么感觉? (noun.) <>这种感觉太好了. (noun.) <>我感觉什么事情不对. (verb.) <>今天我感觉很好. (verb.)

In general,'感到 'can be translated into' feel.', while '感觉' can be translated into 'feeling'.
