Theta Citidel vs Mcintosh MC 502

Looking for feedback from those that have experience with both these sets of mono blocks? I currently have the Citidels and have no complaints I love Theta gear I guess I also love Mcintosh for whatever reason most likely due to growing up with the MAC sound as a kid. As my dad has had a MAC system all of his life. When I purchased the Citidels I was looking for a set of 501’s but three 3yrs ago the used prices were through the roof and the added shipping made the Citidels which were a 2hr drive the choice. Fast forward 3yrs and I have the opportunity to get the 501’s at a better price and am curious what if anything the 501’s due better than the Citidels? I’d imagine the 501’s to have better bottom end but the midrange on the Citidels is pretty magical in my system.
