Budget Travel - SkyEurope or Wizzair?

Pricing out flights from BUD-FCO. Looks like these two LCCs are about the same, within a couple of euros of each other.

I'm leaning towards SkyEurope, because they look like a larger airline (less chance of irregular ops). Any preferences out there?

Sky Europe seems to be more reliable IMO, and flies to major airports. Wizzair flights are delayed very often , and the airline is famous for sudden route cancellations after they have started ticket sales. If I remember correcly, they have cancelled 20 routes so far in this way.

However, Wizz has newer Airbus fleet. Sky Europe uses Boeings 737-500; some of them are showing their age. I would go for Sky Europe.

As a frequent flyer of both airlines I would advise you to go with WizzAir, they have a lot nicer fleet and better legroom as well.
When it come to delays and changes... I must have been lucky because so far I have never been affected by any of those even though I had about 20 flights with them last year.
