If your list is somehow already restricted to just these two options, then it’s CAMBRIDGE as a likely preferred synergy match to your speakers IMO.
BUT …. buying either one purely blind is a helluva risk of a synergy mismatch regardless, that I would not personally undertake. Make the effort to audition them personally ….the final accountability will be yours alone.
CAUTION: Dont get swayed by marketing puffery for specs touting WPC as any kind if a magic silver bullet on amp power.
Audio - amps speakers
(1) The philosophy is clear. An affordable speaker with decent amplification (and source) makes moresense than an expensive speaker with a cheap amp and source.
(2) Amplifier power ratings
Another word on power: If your speakers are demanding to drive you’ll need a suitably muscular amplifier to support them….sure.
BUT …it’s current (amps) that is the key…. Not WPC. WPC specs alone are meaningless. Don’t look only at the headline power figure - see what happens when the impedance drops to four ohms. If the number nearly doubles, then your amplifier has good current delivery and will be capable of driving more demanding speakers.
