The Tamiya Char B is a fantastic kit that just falls together and is actually difficult to mess up.
That said, Bronco makes the R-35 (two versions), as does Heller. Neither are supposedly great kits. I don't think really any of the other options are widely available with injection plastic.
I concur with Jesse and all on that Tamiya Char B kit - I was doubtful when I saw it years back, and it remained too pricey for me almost "forever" ... until I came across one on a HobbyLobby clearance shelf. It's cool and yes, it goes together well! I'd echo any recommendation to do one!
But maybe some filler about the other kits - "R35", etc. and Bronco, et alia... may be helpful?
Heller put out several 1/35 scale French tank kits starting what, perhaps 40+ years ago. These included their kits of the Renault R-35, the Hotchkiss H35, and the Somua S-35. All of these are STILL around on evilbay, etc. Best of my knowledge, the Heller Renault R-35 and Somua S-35 kits are still the only styrene kits available of those tanks. By today's standards, these rank as bears and suffer soft detail, many errors, crude vinyl tracks and poor decals. BUT - IF you have the patience, energy and references, you can get good results - and there have been some great builds of the R-35 and S-35 posted... I've done the R-35 (I enjoyed it, once I got into doing some scratch detailing and stuff, and after a kindly soul gave me some Fruil Hotchkiss tracks, which fit OK and look about 500% better than the original rubberbands... but I'm a glutton for punishment) and the Somua (blah.).
But see the "Blitzkrieg in the West" Group Build on FineScale.com for some stunning stuff with the Somua and also with Tamiya's Char B... and there have been great builds of the R-35 kit posted around. Cool tanks!
Both Trumpeter and Bronco have wallowed in the Hotchkiss H-38/39 mud. Trumpeter kicked off with the H38 short-barreled tank. Trumpeter went ahead and did that Hotchkiss in German service with rockets mounted on it, and did Becker's Marder I H (f) with 7.5cm and 10.5cm guns. They also did the H38-based "Beobachtungspanzer" observation tank. All of these are OK - better than Heller but not something like a Dragon or Tamiya kit. They are the cheapest current French tank kits going, I think - and they are buildable, if somewhat soft and, well, not overly accurate.
Bronco went thru a little evolution with their Hotchkiss - the first release - maybe Bronco's FIRST anything release - kit #35001 - was a good first effort with many errors (I think some pretty glaring - too narrow a hull, some fit issues, etc. see some reviews of it?). Crisper than Trumpeter, has interior stuff, comes with link tracks (TINY links...). They re-incarnated it as a German "beutepanzer" with some wurfrahmen rockets mounted. I have done that kit- I think it kept the too-narrow hull, but it built well and has good detail (MUCH improved over the Heller H-35), and comes with some cool details such as real springs for the suspension. OK, maybe a bit fiddly and besides the point for some...

Bronco went on and corrected some of the -001 kit faults and did a H38/H39 kit (35019). This is pretty nice IMHO. Nice detail, link tracks, probably STILL a slightly too-narrow hull. But it builds well, so I found, and includes some better decals. Bronco followed up (surprised?) with versions of Herr Becker's Marder and Beobachtungspanzer conversions. These are perhaps the best kits going of these odd beasts.
The various Bronco H kits can often be plucked off evilbay or at shows for prices below what you'll usually pay for the Tamiya Char B. I'd recommend them for anyone who wants to build a French tank smaller than that big Char B.
Tamiya and RPM/Mirage put out kits of the tiny Renault UE carrier. Tamy's is, of course, a Tamiya kit - really nicely done, probably pretty accurate. I've done those others... interesting and sometimes challenging

The RPM / Mirage things can come really cheap, and you'll get the wrestling match you paid for!
There's other French WWII stuff out there in styrene.... a slough of Lorraine carrier versions by RPM / Mirage and some by Azimut? as well. Maybe not ideal for the first French tank rodeo, but interesting vehicles. RPM/Mirage have also put out versions of the WWI Renault FT-17 in WWII service, etc. NC.
@Alex You actually have a fair range of cool French stuff to choose from. As The Good Knight said to Indy: "Choose wisely"!
Cheers!
