Smokie - indeed, but we now know.
PC - Based on the types you've mentioned I wouldn't classify the E190 a "Regional Jet", those types tend to be in the 20 - 30t bracket; so based on that information I would recommend staying on the Embraer, it's a very nice type to fly, unlike the awful ATR. The upside is that it's a good type should you wish to move on and the downside, but only within your own company, is that you won't be considered for Command ahead of TP Captains as they stated, but you never know, things can change quickly.
However, I do still firmly stand by what I said originally in that, based on mine and many of my colleagues' experiences, the guys and gals that tend to do better are those that accept anything that is offered to them.
