Trying to Decide.

[BIGGRIMTIM]

I am having a hard time deciding which monitor to keep. I have a Dell Ultrawide U3415W and have really been loving it. Over the last week, I picked up an Acer XB271HU because Costco had a great price. The combination of G-Sync and high refresh rate is amazing. I mainly use my PC for gaming but also do some work on it from time to time. I can't afford either the Asus 34" or the Acer 34". I will be pairing this with a Dell U2715H which I use in portrait mode. Thanks for your help and suggestions.
