On my EX4550, I recall going from 12 to 15 to get some mpls function. But I also recall having issues with mpls services and then later removing those mpls services.

In my view best stability, used by most people (all of my customers are on 12.3 only), and no feature set differences. When 15.1 came out initially there were some concerns, so IMHO most just stayed on 12.3 once it was announced to have continued support. Just my 2 cents worth.

At the same time, I think you might have best results using 12.3R12-S[latest] instead. Both 12.3 and 15.1 will be maintained for life of legacy EX switches.
