To the OP:
If you are tired of switching pedals then it seems like you have one of two choices:
1. get another set of pedals
2. get a new trainer w/a power meter built in
If getting new pedals doesn't excite you, and a smart trainer is actually cheaper, then there really isn't any downside. You can set it up to run like you are now AND you get the added benefit of being able to try Sim mode which, to me at least, is a load of fun.
Therefore, IMO, your question actually is "how tired am I of switching pedals?" Are you $500 tired?
Or if you just need that GAS-induced push to get a new toy -- I will say a Smart trainer is worth it, IMO, exactly for the option of the Sim mode.
edit - one other question - would the new trainer be quite than your old one? Is that something you would value? My Wahoo Kickr is pretty darn quiet. My fans are louder than my trainer. If your trainer is old enough - maybe it's loud??? Just a justification for exploring the switch
