A key difference is interoperability. The quick-release market is fragmented, and many tripod brands use proprietary plates that only fit their own heads and accessories. If you plan to use add-ons like L-brackets, panoramic heads, macro rails, or other support gear, Arca-Swiss style is the safest choice because it has become the closest thing to a shared standard and is widely supported by accessory makers.

Proprietary systems can still work very well. For example, larger plates can give excellent support for heavy camera/lens setups, and some designs include a secondary safety latch to reduce accidental release. They can also be very quick to mount one-handed.

The downside of larger proprietary plates is convenience: they may be bulky and less comfortable when shooting handheld, especially in portrait orientation or with a battery grip attached.

In short: choose Arca-Swiss if compatibility and future flexibility matter most; choose a brand-specific system if you prefer its handling, safety features, or support for heavier gear and don't mind being locked into that ecosystem.
