Yes the essentials feats are very very strong. I can imagine players wanting to snag them.
I think the essentials feats were designed with the idea of "correcting" a lot of the previous feats and the associated feat taxes. Master at Arms is a good example of such. It is "essentially" (no pun) Expertise+, and it works very well in that role. Expertise was not a feat I ever even considered to use, but I have two characters that have chosen Master at Arms, not for the expertise bonus but because of the weapon swap.
