@Dadam Good question, and I love data

- Cannot comment on the hub drive motors, as I've always preferred the idea of crank/mid drive.
There is a regular hill near me which I use as a benchmark for the last 10 years+ for my relative poor climbing ability. My FTP is around 200watts, and thats quite stable.
The summary is both the Creo and Boardman do what they claim, and are very close with the
Creo just edging it, however both are almost twice as quick vs legs only. The difference is in the bikes them selves, one is carbon road bike the other standard
Halfords Alu hybrid, so comparing the 'subjective' ride feeling the Creo is leagues ahead as you would expect.
First graph is tackling the hill on the Creo (bare in mind it this was the 2nd ride out). The Creo has what appears to be an accurate power meter built in - The power reading is rider input not total power output. The Creo is factory stock.
Subjectively the 'climb' felt like riding the Trek Madone, even though I didn't have clip in pedals for this ride. Essentially 'fun' all the way to the top, it must be what pro riders feel like all the time when smashing it out of the saddle.
Second graph is tackling the hill on the Boardman with Fazua motor on max. The Fazua motor also reports power but doesn't like to talk to anything else but the Fazua app which doesn't import into Strava properly. So the power reading is Strava 'estimate' based on figure I put for bike weight and type. The Boardman is running a 'modified' speed sensor

.
Subjectively the 'climb' feels awful on the Boardman. Plenty of 'power' from the motor, but not 'fun' in any sense. Out of the saddle the bike feels every bit its 15kg+ weight despite the support. It was more a case of sit down, spin, and get it over with!
Third graph is tackling the hill on my 7.9kg Trek Madone. This hill is always a killer for me, didn't have HR data on here, but pretty much Zone 5 by the end of the hill. Really interesting to see the Strava power 'estimates' appears to be pretty much bang on, 180watts or so on the analogue bike very close the Creo reported power levels. Add in 200-250watts of 'support' by the motor and you get pretty close to the 380watt+ estimated by Strava for the Boardman.
Subjectively the 'climb' always starts feeling 'fun', but is pure torture by the end. The getting use to the 'speed' of the Boardman up a hill on my weekly commute meant going out of weekend rides on the Trek was heart sinking interms of how slow I was on these kind of hills....hence the justification for another eBike
