Any advise is appreciated.

I am a weekly US domestic traveler, averaging 125 segments and 100,000+ annual miles.

I live in Denver so I have used UA for the past 5 years. I have seen the value of 1K drop substantially in the last 2 years especially, including what feels like 100 people in boarding group 1, about a 15% upgrade rate, and poor service towards my family when traveling together.

My travel now is primarily to CAE, ORD, and DFW, and smaller airports in the south that I will have to go to ORD or IAH to connect through.

In 16 months I will also be moving to DFW.

So the question is, if given the opportunity to immediately switch to AA and receive EXPlatinum status, should I do that now, or wait until later in the year or when I move?

What is anyone's experience in AA vs UA at these levels?

Primary importance is upgrades on weekly flights, award travel for family (I have to get 4 seats for anytrip) and route schedule.

I know i'll have to switch once I get to DFW, and I can get to wherever I'm going between now and then on AA just as much as I can on UA (directs are to the same places and connections are in Chicago or Texas anyway) so is it better to do it now or ride out UA until the end.

thanks in advance!
