I have both, Pro and MP, and Touch Speed MP - very similar and used by Sinner, Andreescu and Gauff.
360+ MP is still perfectly fine as is, nothing missing, deserves all the praise and high notes. New MP is fully usable even for advanced players but it then needs a bit of lead. I have 4g of lead on the at 3 and 9, and that provides more twist stability and swingweight for my one handed backhand. MP like that is still slightly too light for me, I play a lot with juniors and ex-pros, and I need weight, because even if I hit with all I have it still isn't enough against good players. But the MP gives excellent everything, launch angle, bend and dip, kick, stable on slices and volleys etc. It is great for all kinds of shots, very well made racquet. Stable but plush, you can swing as fast as you like, and wherever in the strings you hit the ball your arm is perfectly fine. Great on defence and transition into attack immediately, since it is light and fast and manoeuvrable. A small caveat - MP still requires fast swings, and you really have to try full swings, but its span is wide and large, it will work really well in all kind of intermediate shots, as long as you are aware that you should try to hit harder rather than slower. Racquet like that is made for young competitors who really hit on every shot.
360+ Pro is also great, I also have it with 4g at 3 and 9, and I still need more weight, I'm about to try that next. 18x20 pattern takes the power level down, I would really really like it if Head gave us Pro in 16x19 or 16x20. Its throat area gives it more stability compared to MP, and my swings require it, MP sometimes bends too much for my power. Equally plush and slightly more stable compared to MP. But the Pro however really is Pro, I wouldn't recommend it to everybody. Maybe if you have it strung with a lower tension to maintain snap back, you could get away with slower shots, but otherwise it is made for tennis "like on TV", basically it forces you to play Thiem or Tsitsipas style of play, hitting 120% non stop. And it works great for that, but you can't really slow down. Its other downside is the obvious lack of bend and dip, due to its 18x20 string pattern with an inherently lower launch angle, compared to MP or other 16x19 racquets. Ball trajectory is noticeably flatter and lower. Good players handle that kind of incoming ball noticeably more easily, they just block it, something they can't do if the ball is dipping in, like Sinner's for example. That, and more power, is why I would really love to have a 16x19 Pro.
My next consideration is MP with more lead in the throat and head. I don't like adding weight to the handle, just like racquet engineers don't, because it is mostly dead weight slowing me down, so I prefer not to add a leather grip, but I might try.
Touch MP is too light in the head and needs a bit of lead for everyone 16yo+. It has wide string spacing and fabulous bend and dip, when I watch Sinner or Gauff I can totally recognize the technique provoked by the racquet characteristics. Wider head shape is not great for my one handed backhand, it twists in my hand more easily and forces me to play with a lot top spin on every shot. But a great racquet, needs more than just a bit of lead to give it swingweight and weight of shot. And is also made for junior competitors with fast shots, so you have to swing it and mean it. Also stable and plush, but less than 360+.
