As far as the attenuation, they are both 10:1.
But the design of each probe determines its application.
The Pico TA197 10:1 (blue box) with BNC male and female is designed to connect to Pico's 1:1 test leads or other BNC test leads.
The x1/x10 probe can be switched from 1:1 and 10:1 but it is designed to be used on PC boards. The wire is a much smaller diameter and the length is shorter than Pico's 10-ft test leads. Furthermore, the tip and ground are not conducive to standard automotive testing.
For general automotive testing, get the 10x blue box AES# pt-TA197.
