I'm not sure how honestly this can be answered here but we are currently using SW 2012 and are in the process of planning to upgrade to 2014 (finally!!!). My question is, in your experience using 2015 - how stable is it compared to 2014? I'd love to use some of the new features in 2015 but I don't want to sacrifice stability. Our work is 95% weldments - large weldments - entire oil rigs so if 2015 has some issues in that area - perhaps we should stick to 2014.
Please comment if you have upgraded to 2015 - would you recommend it now or wait for SP1 or SP2?
