depends neither is better in the abstract - it turns on your room, placement or how you will use them.
Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Monitor Audio Bronze C150 is the easier recommendation: it leads on most of the measured areas and costs less. Take Monitor Audio Bronze AMS 7G if its size, looks or fit in your room suit you better. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 83Hz anyway, so judge these on the other rows instead. If your amplifier is modest, vintage or valve-based, Monitor Audio Bronze C150 is the safer partner - the other will want more current or more watts to sound its best.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
