Which eGPU option is best?

Hey guys, looking to add an eGPU to my portable setup to drive a living room TV at 4K 60FPS.

I'm trying to decide between these three paths and would love your opinions on which makes the most sense for performance and value:

Device: Legion Go 2 and Flow Z13 2025

Option 1: Gigabyte AORUS AI Box (Desktop RTX 5060 Ti 16GB) — $740

Option 2: ASUS ROG XG Mobile (Laptop RTX 5070 Ti 12GB) — $1,130

Option 3: AOOSTAR AG02 Dock + Radeon RX 9070 XT — $850 total

For hitting a stable 4K 60, which would you choose? Thanks!
