The P-47 had a larger bombload,
The 190 and 47 had very similar bombloads. Both typically carried between 1,000 and 2,000 lbs on operational sorties. Both could potentially carry upwards of 3,500-4,000 lbs; if fitted with an extended tail wheel the 190 could even carry the big ~4,000 lbs bomb the AH stuka carries. I consider the two aircraft equal in this regard.
was faster
Up high the 47 was faster due to it turbo-supercharged engine. However up high is not the realm of the Jabo. The Jabo flies low as a necessity of its mission.
was more survivable,
I regard both aircraft as equal in this regard. Both had tough radial engines and had tough structures that could take a lot of punishment.
I'd hazard the 8 0.50s were better for ground attack then the two MGs and 2 cannon of the 190,
I'm quite sure they weren't. While the .50 cal worked well against soft skinned vehicles they were practically useless against infantry and armor. The 190's 20mm fired a combination of AP and HE shells that had greater penetration against armor (AP) and much higher lethality against infantry (HE). A .50 cal round landing one inch from a soldier's boot does nothing. A 20mm HE shell landing ten feet from a soldier's boot will burst his eardrums and shower him in light shrapnel; at best he will only be a casualty, at worst a fatality.
had a longer range
Both aircraft had similar range on internal fuel. As Jabo the majority of sorties would be close air support for ground forces with the Jabos flying from forward airfields. However, for longer range missions both aircraft had the option to sacrifice ord for external fuel; usually a centerline droptank. For even longer range droptanks could be carried on the wings while carrying a single bomb on the centerline hardpoint. In this configuration I consider the 190 to be somewhat better than the 47 since it could carry a 1,100 lbs bomb.

was more effective as a fighter.
Only at higher altitudes. At lower altitudes (where Jabos need to be) the 190 was the better fighter IMHO.
It was the ultimate ground pounder/versatile Jabo.
It was very good indeed, but I consider the 190 to be superior in the Jabo role.
The F4U was a better dog fighter then the 190F, and I always thought it was much faster.
The 190 has always had a speed advantage against the F4U (not by much late in the war though). Even in 1941 the 190 was a 400+ mph fighter and rudely demonstrated that turning never wins an air battle.
