Can anyone suggest a really good premium wet cat food to try for my two?

They've tried the dry James Wellbeloved previously but Alfie gets sick from it, so I spent a while having them on different foods which was a nightmare at dinner time and they prefer wet food, so I've found a couple of different premium wet foods but need advice on the best ones

Jess suffers from allergies which the vet thinks is linked to the food she's currently eating (Whiskas), hence the change.

I'm looking at:
Royal Canin
Hills Science Plan
Iams

I realise the price varies and Royal Canin is expensive in comparison, but is it the best quality. I want to make sure their diet is as natural and good for them as possible, in the hope it can alleviate some of Jess's allergies while not making Alfie ill....

Dry food isn't really an option however whichever brand I'll probably buy some dry to compliment the wet.

Open to other suggestions too....
