There are differences however including most notably more adjustability in the form of Titleist’s SureFit CG technology that allows for more specific spin rate and launch angle tuning. The TS3 also features a more traditional pear shape and tends to produce more of a mid-launch as compared to the TS2’s higher launch.
According to Brian Schielke marketing director at Srixon Golf the newest line of Z Series woods don’t simply represent an evolutionary improvement over the company’s past models but rather a “revolutionary” one and for good reason.
Among those I’d start by looking at models from Bettinardi Evnroll SeeMore Happy and Bloodline. Each of these companies make high-quality products at varying price points. Furthermore they can perform exceptionally well provided you find one that fits your stroke eye and feel preference.
