EGT will give you "real time" picture of what's going on in the combustion chamber.
CHT was never really a tuning device as much as it was "insurance" that you didn't overheat an engine (kinda like water temp on your car.)
Yea, CHT is better than nothing, but only slightly.
Keep in mind that on certain engines (small plate flatheads for instance,) that they make the best power with very low egt and an overly-rich condition. If you tune/lean a purple plate flathead too 1150egt, I can guarantee that you're leaving power on the table. This is somewhat true with air/fuel ratio or O2 sensors as well, so you've got to be careful.
A/F lambda really is convenient and you can use it real time on the kart (sans dyno) for your practice sessions.
Make up a clamp and brace to mount it to the end of your pipe/muffler and you can easily add it or remove it from practice to race time. Some go the extra effort to create a second pipe and change pipes = hard on threads and takes longer.
Whatever route you go, any data that you can obtain is valuable -- some obviously more valuable than others.
How you use that data is up to you.
