Have the MP7/MP5SD buffs for Season 4 been noticeable?

I've been a MP7 lover for a while, but Season 3 it was just too difficult to ever purchase one due to the MP7's high cost and stats being too comparable to a MP9. The decrease to $1400 however as well as its higher damage-at-range has made a MP7 a very common buy for me on CT Side now.

I'm curious what's everyone's experiences been with the MP7 and MP5SD. Have you began to use either of these more now? Has it become more popular in your games? Are you a fan? Or is there still something lacking from it compared to other SMGs.
