I have switched to light sussex because I hatch them and the cockerels are big and meaty and the hens lay large eggs and they dont go so broody.
I only have one welsummer but the eggs are beautifully brown and she is a proper character bird.  We have had a few LS / welsummer crosses but all been cockerels so far.

Out of those three, I'd go for Sussex if you want meat as well as eggs but if you have a market, get a few hybrids to keep you going in the coldest, darkest months. 

There are some based on LS which look pretty meaty...
