What's weak about it? Look at the blockchain and you can see how much better privacy a WabiSabi coinjoin provides than a Whirlpool coinjoin yourself:

The Wasabi model doesn't offer this sort of indefinite mixing because it doesn't make sense for one user to be charged for the blockspace a different user consumes.

On the second point, having more pools absolutely does lead to less privacy compared to combining all inputs in a single round because you eliminate all of the potential probabilities that are created from the composition of each additional input and decomposition of each additional output. Compare these two coinjoin transactions:

WabiSabi: https://mempool.space/tx/01a1a055719129397fb8344b5a09e6cfe72868c8e1d750e621d8b580c96bf77b
Whirlpool: https://mempool.space/tx/1825e9f7f0548fb4957d389b20e0e46d1ccc9ee50a75ebd19f7a49cdee761e50

In the WabiSabi coinjoin, there are 16 inputs for 0.001 and 13 outputs for 0.001 compared to 5 of each in the Whirlpool coinjoin. We can see the anonymity set is higher at face value due to the round's size, but the more important design choice is that there is not a 1:1 ratio of inputs to outputs of the same value. The 3 "missing" 0.001 outputs that are needed to complete our naive assumption don't exist since because they were either broken into smaller standard outputs, or merged into bigger standard outputs, inheriting privacy from all other inputs and outputs in the transaction that are not equal to 0.001 exactly.
