I have EngraveLab v6 and I would never use it on my laser.
It seems full of bugs and is sometimes quite unpredictible. It's Corel every tme for me.
I have to use it on my rotary machine and most days I swear at it. (And I have been using EngraveLab for years) I used to like version 4.95 until I became more proficient with Coreldraw.
I guess it really comes down to your own preference and how you carry out your work. I have obviously failed to come to grips with the changes from Version 4.95 to Version 6.

I don't know how to answer your reply other than your right with comfort level.. I use both corel and Engrave lab and I think Engrave lab is great... so there.. lol...

Every thing depends on learning and feeling good with what you use.. and not having bugs.. or glitches..
