To throw a similar experience into the mix... I agree on all counts, particularly around silence & efficiency - especially on the MBPs where the fans will actually turn off when not needed. I've been a long time Windows user (20+ yrs) and have built my own PCs for nearly as long. My most recent 5900X + 3080 FE setup with 2x Gen 4 NVMes is amazing, but it's not the most efficient. ~95W idle and can top out around 200-400W depending on the use. The (base) 14" M1 Pro I got launch day has been great overall, just really smooth/snappy in real-world use, where lately I've hit snags on Windows and MS software. The 14" M1 Pro maxes out around 35W or so (including its display). Desktop's more like 500W including displays. Great battery life on all the new M1s, it can do a full day at 8-14+ hours of medium/heavy use depending on your use/multitasking. It doesn't have to throttle down for thermal or power reasons like many recent Intel laptops (including a previous and recent-gen XPS 15 - which was much noisier by comparison). In terms of quietness, I have the 3080 FE undervolted to typically only top out around 240W with under 2% performance loss. It typically runs around 55-65c in games without the fans being noticeable. 5900X is cooled by a 240mm AIO so it too is able to maintain reasonable temps running nice low fan speeds - only up to around 1050 RPM for sustained max loads which is still quiet compared to most other peoples' desktop PCs I've seen. The 14" M1 Pro has never been audible above the idle fan speeds on the desktop (which run at ~550-600rpm and are also nice and quiet). The MBP is virtually always silent unless you manually crank the fan. Direct sunlight or somewhere very hot the fans might kick up a little more in response, but for me it's never really noticeable or even on or audible under normal use, and I like quiet devices.
