It looks and is slow of course, but sometimes analytical solution is good. Larger circuit though could become too difficult to analyze as this and if there is not inverse functions required found it can be harder to give final solutions.
I didn't yet see anyone analyzing MOSFET circuit with this. Result can be checked at "steady state" (t->Inf) (if the switches operate only short period), but other time points can be riskier.
If its easier in this problem to use node voltage rather than current loop method is possible, because the final results is requested as voltage.
This case it looks like if KCL used instead of the KVL it easier for finding voltage values. But with KCL its difficult to find the right current directions.

What amazes me is that Zahi makes math errors and no one in the class catches his mistakes.

At 25:03, you write Current1's denominator incorrectly. You put "+3s" as the middle term instead of "+5s". The rest of the solution is affected by this mistake.

the first equation you multiplied by S and the second equation you didn't... I was wondering if it's correct to do that? Thanks

I think we have a wrong kvl in the first equation. we should have - 3( I2 -I1 )
