Agreed
It won't make the slightest bit of difference to any firm what you train on. You won't be looking at air taxi work for a long time. And even then as puppy says you don't get a seneca type rating. Also an IR course is normally only 15 hrs in the aircraft. Plus 6 for the multi doesn't exactly stack up to vast amounts of experience.
For what it's worth from your list I would go to Bristol on what I've heard. They're reputation is very good, I know several who have gone there. I couldn't recomend Tayflite. I see lots of people go through there and not many do well.
But as everyone will tell you go visit them.
