It depends...what I'm turning. There are times when I'm doing a long peel and trying not to be too aggressive with the cut, I reach for the oval. The oval I have isn't as thick and the angle is less extreme that my traditional.
I do like the traditional for its solid feel on the tool rest, the oval moves more. The sharper angle of the traditional allows me to get into some spots that I can't reach as easily with an oval skew.
I will say, getting a consistent grind on the oval is more difficult due to its preference to 'roll' when sharpening. I could probably make a fancy jig or buy one, but I've been 'free handing with support' on skews and scrapers for a long time.
May all your turnings be smooth,
