Everyone has their own opinion, but your assumption that a 3-way cabinet with a subwoofer is better than everything else probably wouldn't fly with many here. Depends on what your goals are, but lots believe single-drivers are the best, others prefer two-way bass reflex with no crossover or with a minimal crossover. Many just don't like subwoofers in the mix, finding them boomy and lacking definition, especially compared to a 15" or 18" woofer moving lots of air. Everything depends a lot on the amps, source, room, and what kind of dynamic response you want. I'd encourage you to explore your options more!
