I'd still prefer Reina over Carson any day of the week. He has more attributes such as his distribution and I believe he comes off his line quicker and to greater effect.
When I've seen Carson this season for Charlton, he hasn't really dominated his box or come for a lot of crosses etc. And I have seen him make some mistakes for them as well, but all keepers will make mistakes - they don't always get punished for them though. He looks like an excellent shot stopper though, and I'm glad he's having a season's worth of experience at Charlton in the top flight. That should help his development in the future. And he's still young of course. He's younger than Reina isn't he?
But right now I'd still prefer Reina. Easily one of the most reliable keepers in the Premiership.
