I drove a Cayman S for 10 years, so not quite the same but similar enough.
I loved it, but i like driving go cart type cars rather than fast saloons.
The 718 Boxster is of course now a turbo - i'm no petrol head, but there are plenty who don't like the dull noise the turbo makes. Especially when the noise of the Porsche engine was a good part of its charm.
I test drove a turbo 911 (not the 911 Turbo - they're all turbos now) when they were introduced in early 2016. The drive is absolutely fine, the lack of the distinctive noise i can see is an issue for some.
I went for a normally aspirated 911 GTS instead, and needless to say its an amazing machine - the noise when starting, or when blipping down through teh gears is awesome.
I doubt you'd be unhappy with the 718 Boxster though - noise aside, which is a bit subjective, Porsche make pretty fantastic cars. And the 718's are pretty quick.
