It's really one of those questions that only you can answer. To me it's worth the extra (leaving aside that my machine is 8x4) as I use nesting, toolpath templates and gadgets every day.
Fortunately the way the upgrades are priced means that if you buy the desktop version and later decide you want the Pro version then it won't cost you anymore than if you bought the Pro version in the first place.
Pro also does gadgets, which I really enjoy because I've written a couple of my own. I agree you're just fine without the Pro options, especially to start with. You may eventually decide you'd rather have Aspire over VCarve in the end.
