Wet tantalum is not at all bad with leakage, but will need a permanent bias to keep it that way. I did take 100 that had been in storage for around 2 decades, and measured them, half with no reformation, and half with them connected to 20V via a 1k resistor for a night. No difference really in capacitance, ESR or other parameters, just some were off the bat shown as near ideal capacitor, and others were shown with slight leakage of around 100k-1M. they were all 10uF 25v units. Do not use rubber seal ones, they only last 5 years like electrolytics, while the glass seal ones last till they corrode through from the outside. Rubber seal is cheaper, but not worth it if you are paying for tantalum. I was changing them by the hundreds.
But for low noise use polyputthekettleon, and use those in sealed housings, as the bare ones are a little sensitive to environmental parameters. Bare are cheap, and often available in SM forms, but temperature and humidity swings will cause havoc with leakage, plus PCB cleaning and solder flux residue as well.
