I'm finding it hard to justify tantalums. I looked at prices for input-side filter caps on a quickie design I did last weekend. ~$1.20 in single quantity for a 22uF 35v MLCC in a 1210 package. Somewhere in the $4 range for a bigger tantalum-polymer at the same capacity, and equivalent working voltage. Of course they both get much cheaper at lower voltages, but this is pre-regulator, where I want to be as lenient as possible. (I ended up settling for 22uF 25v MLCC, which was half the cost.)
When it gets too pricey to fit a MLCC, I just go directly to electrolytic. I'm a little put off by tantalum temper tantrums WRT reflow solder damage and applied voltage thereafter. At least when a 'lytic fails, it pops and makes confetti, rather than bursting into flame. IIRC, the polymer variety aren't supposed to be quite as violent though.
