I'd judge it the same since EA had the option to put more resource but didn't. Sucks for that team, but EA would ultimately be at fault.
Fifa isn't made in UE4. Nvidia has had a hand in development of this particular engine and Nintendo has tuned the Switch (along with Nvidia) to make sure that it handles UE4 from a development pipeline extremely well. It's also almost certainly using fp16 in a mixed precision to meet this performance... Even if EA is using frostbite for Switch version of Fifa (not saying it is) these advantages would not be there, I think we will see a more modest performance because of these factors.
People shouldn't be running with what Switch can do in UE4 and applying it to every engine, UE4 is going to be much better at drawing out the Switch's full performance than other engines.
Fifa can of course look good, and play well, but it's not going to sit side by side with the PS4/XB1 version (even if it wasn't custom) and be anywhere near what we are seeing here, this is a best case scenario for Switch honestly and was what I was talking about in my speculations of performance because in all honesty, Switch is punch way above its weight on paper here in this game, (like twice as high) So just a caution to people who look at this and see what Switch ports should be, it's not... expect on paper, the Switch version of a PS4 game to run at what we see undocked here, docked in those other games, because that is what on paper, you'd get with direct ports, that is to say if the PS4 game is 1080p, you might get 540p docked with a very similar performance, or if the PS4 is 900p, the Switch docked version would be 480p, this is the cost of development on a tablet without taking advantage of its advanced features.
Any developer should be able to navigate these waters well enough though, fp16 in mixed precision isn't too hard to implement and would mean a decent increase in performance, and nvidia generally does perform better per flop, but again this is going to be a developer taking advantage of the platform, so maybe Fifa will look like a current gen game at reduced but not too far reduced resolution and graphical effects, I feel ~30% of PS4 performance is obtainable in most multiplat games for Switch. Just not the ~40% of PS4 performance we are seeing in snake pass.
other games that have had poor performance have been criticised, for sure. So if this one has performance (resolution in this case) issues, shouldn't be different. Yes as an indie developer i can understand it, not that i like it, but it is tolerable somehow, but maybe they should have focused on a single platform or released the game in a few months. They probably thought it was better to deliver a 'not so polished' game asap because the lack of games on Switch, and being a simultaneous release with PS4 too would give them a better chance to sell more copies.
And i don't know if sub native resolution on switch is good, on vita it was quite noticeable when a game wasn't running at native resolution so...
I still think Wii U gamepad is a better comparison, they have the same size screen and basically giving the same resolution (480p streamed and compressed vs 475p with AA and running on the device) It should look better on Switch than it would on Wii U gamepad, and nearly as many people have used these devices, so seems fair. Personally, it's all a big step up from the 3DS which was my favorite platform a few years ago, so I think I'll be fine with this. I also tend to run sub native resolution on my own 27 inch PC monitor and bumping up effects and frame rate, so I'm not entirely sure how much the average gamer is going to care, heck I think the main issue is the number itself and not how it looks, but how people feel about the numbers.
Edit: As a hobbyist developer myself, I would actually target native resolution on the Switch handheld, but I'm a single developer, who is focused on game design over graphics directly, so whatever I could push through UE4 in a ~200gflop maxwell GPU @ 720p is going to be what I'd be after, I would want 60fps and use dynamic resolution to maintain that smooth gameplay, but I do have to respect how sumo wanted to display their game, it does look really good and the AA seems to help, so while I would do things differently, I think what they did is perfectly valid.
