Unless you are hugely driven to get a command, giving up a position in a large carrier where you have a lot of seniority might be unwise. The RYR lifestyle seems to suit some, but if you jump ship and don't like it, you are trapped as you will then be a Capt. and it is difficult to go elsewhere and retain your command, something which is difficult to give up. Also, seniority means job security in an insecure industry, assuming your current airline operates LIFO.
In the end, lifestyle is the most important factor in a career in aviation, and unless there are urgent reasons for you to leave, I'd sit happily in your seat waiting for your turn to come.
