B Clarinet to Tenor Sax?

I've played both, and for me the b clarinet is easier, but that's just me. The s arnt really similar because it's in a different key. I've never counted the keys, sorry. And if you're going to be in Marching band it would probably be best if you played the alto, and if you play the alto the s for the bari are the same, and the bari is a wonderful instrument to play, it's my favorite, it's my concert instrument. And it's fun to play in Jazz band too.
