I wouldn't waste your money on something that only performs "better by a little". You're much better off having a little patience, whether that means waiting for what you actually want to return to being in stock OR saving a while longer to get a better part. Otherwise, you're just wasting your own time and money. Just my 2 cents.
Truthfully, if you want a high quality part with really good performance, you'd be looking at Noctua, Cryorig, Phanteks, Thermalright (NOT Thermaltake), Scythe or Even Be Quiet coolers, although I feel the Be Quiet coolers need the fans replaced with Noctua fans to be both quiet AND perform well. Be Quiet fans are low noise, but they seriously underperform in most testing.
Those are the cooler manufacturers that have consistently shown that their products excel in rigorous testing and long term quality. If other manufacturers had products in the same conversation, they'd be known to me. Certainly if MSI did, as they have a huge presence in the US, but not for coolers. And there is a good reason for that.
Even if you have to import a good cooler, or look around a bit more, might be worth your time to do so, but again, totally up to you. You are the one that has to live with the decision and if you can, then it's fine.
