Which antenna ?

This spring sees a big change at my home QTH, as I will be installing mini beam. Up until this weekend I had my heart set on a MA5B. All was well, but a few days ago I discovered the TGM MQ26-SR. a hybrid quad, which on the face of it seems pretty good. It has some amazing gain values and all from a small package. The crucial question is this - Which one to install? I’ve added the specs to each antenna below and a link to their respective web sites. i think i know which one i will be going for. but it makes for interesting reading

Details for each of the antennas are taken from their respective websites:
