Total beaxst before monster maker?

Going to finish size next month and want to choose a more strength and power focused program after so I can keep alternating between it and size for the next year or so. Was going for beaxst however after seeing monster maker it just looks like a better version of beaxst since you can target a specific part to improve it more than the rest, since my chest has always been lagging behind I've found this to be quite intriguing.

It seems that beaxst is recommended before this however I'm not sure, this seems like a more appealing option and since I'm going to alternate for a while I want to choose the better and more replayable program. Any thoughts?
