M gets into the revs faster and reaches red line quicker. As far as power, the Maser wins. The Maser slaps me into the seat more. I added a Corvette to my stable. Its an '05 C6. This beast has long gear ratios and will go 60 miles in first. Way different than the M3. The weight of the Vette and the same horsépower puts it way out in front of the Maser. The shifting is smoother too. As far as coolness, the Maser gets the nod. whats nice is they are all different.
