First off, 1080i is interlaced video which is essentially half the FPS/ but with each frame 'stitched' together, really doesn't make much sense in this application.
Regardless, from my own personal experience it is really just down to the game. Some games, like PUBG, I find that 3440x1440 resolution really does allow me to see people better. Because of the nature of the game, a lot of the time you are looking for just a couple 2-3 pixels out of place. That is a lot harder to do at non-native resolutions, and resolutions that are too low can obfuscate further enemies.
On the other hand, with a game like APEX where you are less likely to be in combat >300m then resolution becomes less of an issue, and having a monitor that is 1920x1080 will fare you no worse than 2560x1440 or even 3840x2160, perhaps even better due to the frame rate increase that comes with lowering resolution (plus typically lower res monitors are capable of higher refresh rates depending on the model).
Currently I have both an AW3418DW and AW2518HF and can say that both are absolutely excellent for gaming. The 2518 definitely feels a bit smoother, but both are snappy and responsive. The biggest difference between the two is form factor, which, while ultrawides can actually be very nice/useful, in a competitive environment they tend (for me at least) to provide an excessive amount of screen space that can leave your eyes strained from having to carefully scan the entire monitor. Smaller monitor -> less scan area. Another aspect to consider for visibility sake is that you will be able to spot better and track better at higher framerates. This is due to the way you notice and track changes in your vision, more steps (or frames for that matter) provide your brain with more/better tracking information and allows things to be seen/looked at easier when moving quickly. This won't matter at all if you are playing games that don't tend to feature a lot of object/player movement but can be for sure beneficial in fast pasted gaming.
That being said, having the choice of both monitors is really the best of both world. I am able to play sim/casual games on the ultrawide for immersion, and competitive games on the smaller monitor to help avoid eye strain.
