Even though I have long been and continue to be a fan of vintage tube equipment, in my mind the decisive factor choosing between the MC225 and the LM amps that have been mentioned would be the condition-related risks associated with the approximately 50 year old MC225. And even if you were to find an example appearing to be in excellent condition and/or well restored, the possibility that you may frequently find yourself wondering if it is truly performing as well as it once did.
Also, as I recall the MC225's reputation for providing outstanding sonic performance in relatively modern systems was largely established and solidified during the 1980s and 1990s, when roughly speaking it was just half of its present age.
Finally, as always I would attach great credibility to the comments by Charles1dad.
Good luck. Regards,
