Totally agree, stainless steel is usually the safer bet long-term. But don't overlook plastic fittings either... I've had good luck with quality PEX connectors—no corrosion issues and they're pretty eco-friendly since manufacturing uses less energy overall. Worth considering.

Fair point on the eco-friendly angle, but from experience, plastic fittings can sometimes be a gamble under sinks. I've seen them crack or loosen over time, especially if there's frequent temperature swings or accidental bumps from storing cleaning supplies. Stainless steel might cost a bit more upfront, but it's usually worth it for peace of mind. Just my two cents after replacing one too many plastic fittings on emergency calls...
I've had mixed results with both, honestly. Plastic fittings held up fine in a rental I had for years, but in another place they cracked after just a few months—probably due to temp swings or tenants jamming stuff under the sink. Stainless steel has been solid every time, though pricier upfront.

Yeah, plastic fittings can be hit or miss depending on the environment. I've seen plenty of cracked plastic fittings myself, especially in kitchens where people tend to shove cleaning supplies and trash bags under the sink without much care. Stainless steel is definitely pricier upfront, but honestly, it's worth it in the long run. I've rarely had to revisit a stainless steel fitting once installed properly.
One thing I'd wonder about though—are you guys using plumber's tape or pipe dope on your fittings? I've found that even quality fittings can leak if they're not sealed correctly. Also, curious if anyone has tried brass fittings as a middle-ground option? They're usually cheaper than stainless but tougher than plastic...
I've had my share of plastic fitting nightmares too—once had a tenant who thought under the sink was the perfect spot to store a bowling ball (no joke). Needless to say, plastic fittings didn't stand a chance. Brass fittings have been pretty solid for me, though. They're not as pricey as stainless steel, and I've yet to see one crack from temperature swings or random bowling ball storage...
