One of the main reasons for going with an “industry standard” NLE is if you need to interchange projects with other editors on a regular basis. If that’s the case, then go ahead and make the switch. I deal with Premiere, FCP and Avid users periodically and never have any issues exchanging projects with them. Pick a common format and stick to it.
If you have to deliver material for broadcast, there are several users (me included) on here and other Vegas forums who deliver product using Vegas.
The final decision is yours to make. Just make sure that you go into it with both eyes wide open.
