Ah my mistake, I didn't realise there was a flat bar Diverge. That makes sense. Love the Marin bikes! Had a lovely mtb back in the 2000s. Plus their gravel bikes are such good value and great geo.
I'm demo riding the Diverge Comp E5 EVO on this Friday, a real hard terrain ride + a steep climb. If I'm happy, I will saving for the Expert These bikes are not cheap unless it is post season clearance sales!
Tried one today. Here are some rapid-fire thoughts. Keep in mind these were very different spec levels, and very short tests.
Skitch (base, flat bar) against Creo 2 (S-Works, drop bar), both on similar sized tires 43/42 respectively iirc.
Initial impressions / Comfort / Handling
Excellent build quality
More aggressive seating position
Comfy, quite wide flat bars, fairly supple frame / Creo 2 more comfortable ride and less vibration to hands, less impact over big bumps
Extremely maneuverable - while riding felt lighter and more nimble than Creo 2
Felt slightly lighter when picking it up too... The shop said they weighed it at 31 lbs
Power / Noise / Shifting
Motor was quiet, frequency range didn't stand out as annoying (the salesperson rode along on a Velotric with like 16 KHz wine -- annoying!) Creo 2 has the edge here because I rode it in a parking structure with more reflective surfaces and it didn't stand out as much.
Motor power felt very natural, Creo 2 again just gets the edge.
Creo 2 felt a little more powerful too. We rode on a fairly windy day, and both bikes were pretty low battery (~15%). The manufactures will likely decrease power output at different SoC around there, so not a fair test. Definitely powerful, nobody should worry about that one bit.
Motor power increase/decrease on a little thumb throttle thing on the left side, Creo 2 has it under the handlebars which I prefer
Shifting not as satisfying or easy as the etap system on the Specialized bikes, not a big deal but I've tried etap and enjoyed it (easy but pricey upgrade for Skitch..)
Easy to ride unpowered
Utility / Misc
Fewer/no mounting points for panniers. Would people be running panniers on the fork of Creo bikes? I see some people swear by that style, but my impression is rear panniers would be more stable.
Super wide tire clearance (up to 54mm iirc)
Color: one color choice
Dealer experience: both excellent, both beyond all other stores I've tried. Dealer offered to customize the bike exactly as I wanted (SRAM components, tubeless, etc.)
Overall Specialized seemed like a more mature electric product, especially knowing all of the customizations that are possible in software (to be fair I have not researched this for Santa Cruz)
Skitch a little more fun, Creo 2 a little more comfortable. Both extremely high quality bicycles, and the best e-bikes I've tested.
