Plenty of options out there but I like my Cadac 2 Cook, lightweight in comparison to some others. Comes with 2 saucepan stands and also a griddle plate and flat plate, so you can easily switch to suit which meal you are planning on cooking without needing to take loads of pans with you.
I run it off of a small gaslight cylinder or the small patio gas (calor) bottles. It kicks out plenty of heat so even on a windy site it doesn't take long to boil a pan.
You need to consider the Campingaz 400 series double burner stove.
I've got one, I run it on Calor Gas Propane cylinders.
It's the most powerful regulated stove I've used and running on Propane it works all seasons.
Before going to France you need to refill the bottle if in doubt.
The plastic stand is fragile, I dropped it and broke a bit off.
It is supposed to be wind resistant but I tend to turn small tables on their sides to build wind breaks around it in high wind conditions.
I have the one without the built in grill. The grill takes up a lot of space in storage and transit and I've yet to meet a grill I'm happy with.
The press button ignition is really good while it works.
So if you're going to use a refillable gas cylinder buy this Campingaz stove, run it on Propane and never drop it as breaks bits off. Always carry small tables that can be used as windbreaks.
If you are thinking Campingaz Chef type, (https://www.campingaz.com/uk/p-27581-camping-chef-folding-stove.aspx), not sure there is much to choose between them, BUT ones with wind breaks on 3 sides are far preferable to none or just back (folded up lid), thing heat MUCH quicker if wind is not blowing flame/heat away, AND you waste far less gas!
Don't put too much value on having a grill, they are pretty useless, take forever to grill or toast and do so rather unevenly!
Separate wind breaks either stand alone or part of a cooker stand are just as effective as ones built into stove, but some form of wind break is invaluable.
Although they're not made anymore I reckon the Campingaz Kitchen Plus - two rings or a griddle and the regulator can be swapped to whatever type of gas you prefer to use - from a standard industrial propane bottle all the way down to a disposable C200 with an adapter. You can usually find one being sold on Ebay/Gumtree or Facebook marketplace at a reasonable cost. If you are a Facebook user here's a link to one for sale at the time of writing (my experience most people will wrap it up to post or drop off at a local Hermes/Evri courier drop-off point).
Depends on whose with you camping, If you have children, try to buy one with knobs you have to push before turning. Little fingers have a habit of messing.
