The price difference will tell you pretty much all you need to know. The Evolve Plus is a decently built wax pen, dont get me wrong, but the Utillian 5 is premium like the Source Orb 4 Premium Kit.
Yocan tries to set itself apart from other wax pen manufacturers with their unique atomizer cap system, which prevents splatter and allows the temperature around the coils to remain hot for a more efficient session. However, the design tends to be a bit flawed as the threads for the caps can easily get gummed up with cannabis extracts.
This also can be said for the threading of the mouthpiece of the Evolve Plus, which tends to get stuck in place with oils. If you dont feel like dealing with gummed up threads, the Yocan Magneto with its threadless design is worth looking into.
The Utillian 5 avoids this by avoiding the use of threading, opting for an o-ring system for their mouthpiece. Splatter is not much of a concern with the Utillian 5 either with the way the black ceramic wicks and the way the mouthpiece is closed off to prevent splash back.
Utillians coils are far superior to the Yocans and will easily outlast the Evolve Plus dual quartz coil which tend to only last a couple weeks before needing replacement. We found with the Utillian 5 we could use the same coil for months without issue, only needing to replace them when they became too dirty to clean.
If youre willing to shell out a couple extra bucks, the Utillian 5 has a clearly superior build. It is well machined and rugged. The atomizers use black ceramic instead of quartz, which is much more porous and allows the wax to soak in and wick rather than slip to the bottom of the cup. The end result is more vapor and less wasted wax.
The Utillian 5 wins this category.
