Well, the keys don't feel the same. So if you're used to Reds you'll need some time to get used to it. Depends on you whether having something more silent than MX Red is worth the risk of you possibly liking/disliking the new switches.
IMO, the Silent switches aren't "that" much quieter. But then again, they're not bad switches. So whatever you go for, it'll be a good choice here.
