Tough one, it'd depend on the actual rifles.
I've seen some pretty beautiful Exploras and Super Exploras.
If that would be a Super Explora with drop locks I'd likely go with the WR.

I can't imagine one being more or less easy or difficult to load.
I'd expect both rifles to shoot about the same.
I'd also be in fast contact with a few fellows who'd owned both and get their opinion..!

Hang in there, such guys will likely soon chime in...

Cheers
