The Trigger is the better of the Cherry MX boards you mention(since it has a standard layout on the main area of the board so you could replace the keycaps at some point if you want, which is one of the advantages of having Cherry MX switches), but if you are willing to order a board from the site you list the Topre boards at, I'd much rather get the KUL ES-87 with Reds than any of the boards you list.
If you can find another board locally with MX Reds and standard layout made by Filco or Ducky than that would also be a good one to get.
Topre is fine for typing, it has a very particular feel that is very different from any Cherry switch, but Reds are better for gaming, considering you already have a board for typing. IMHO, the 55g is the best if you do buy Topre. Topre have an S-shaped force curve like most rubber dome boards since it is also based on rubber domes, but it feels better than most other rubber dome boards. Still, I don't like them, personally, and it's a lot to pay for a board you may not like, especially if it has to be shipped from overseas.
