Comparing a capsule to a meal replacement is comparing a modifier to a meal, and the meal usually matters more.

What shakes actually do
A controlled-portion, high-protein replacement removes a decision and caps the calories of one meal. That is the entire mechanism and it is a genuinely effective one — portion control by structure rather than by willpower. Trials on meal replacements are reasonably favourable for exactly this reason.
What they do not do
They provide no thermogenic effect, no energy benefit and no help outside the meal they replace. They also do nothing to teach portion judgement, which is why regain after stopping is common. And a poorly chosen shake is a sugar drink with a health label.

One changes intake, the other changes expenditure and appetite around normal food. Someone whose problem is a chaotic lunch benefits far more from a shake than from a capsule. Someone whose lunch is fine but whose 4pm is not benefits more from the appetite and energy support.
Using both, if you want
There is no interaction problem. A high-protein shake at lunch and SodaSlim in the morning address different failure points. Just be clear which problem you are actually solving — our protein guide covers the food side.
