Who could possibly say? The difference between stock and inserts is considered substantial by most who have done it. Same with M3 bushings. Are M3 bushings than just inserts? Likely, but where's the data on how much better? Who could possibly say? What data could they present that applies to you and your car?
It's even more complicated than that. It all depends somewhat on the condition of your existing bushings. How can you judge that?
Powerflex also makes a harder ("race") insert. I'd guess their effectiveness falls in between the standard bushing inserts, and the full M3 bushings. Exactly where, who could possibly say?

You have to consider installed price. Whether you are qualified to work on critical suspension bits, and have appropriate tools. Pressing out the bushings. Access to BMW shop manuals for specifications. Access to new fasteners where BMW calls for them.
And then guess what will work for you. Inserts, bushings, professional installation or not. How much you trust the aftermarket manufacturers and how much you want the BMW label on everything. The only thing you can be fairly sure of is that most people who have done or had done either mod like the results.
The other thing you can be certain of is that there are plenty of uncertainties and some risk in messing around with your suspension. Not the least of which is how much you rely on random amateurs on the Internet, of unknown qualifications, giving you a very few words on complicated issues. Like me.
