Nothing wrong with US companies like Delta, Kohler, Moen. Long histories and good warranties. Perhaps the issue is availability. Also, sales people are not likely to recommend a product that can be easily price shopped at the big box stores.

The bigger question is product availability if you're wanting other trim items to match. I waited 4 months to get Delta faucets from plumbing supply and they were still not available at time of plumbing install. I had to get something else from box store, which are different styles by Delta so at this point I just wanted finishes to match. Hansgrohe is mentioned a lot on Houzz as a quality faucet. Doesn't matter which brand you go with, it's only as good as its warranty protection.

I have had Grohe and Delta in my past house and current house. My current house is going on 4 years old and no problems with any faucets. With my previous house we only had 2 issues for the 14 years we lived there. One was with the Grohe shower dripping. Grohe sent us new part free of charge. The other was with the Delta kitchen faucet side sprayer. I forget if it was the sprayer itself or the hose but Delta sent us a new part free of charge.

Depends on your budget and what style and finish you want.

Moen and Delta are high quality for relatively low prices - although that is relative especially if you want a higher end finish or trendier style but they are still less expensive than other brands and both have lifetime warranties.

The brands you mention are both high quality brands but are more expensive than Delta or Moen and considered to be more upscale. They might have styles you prefer.

When I remodeled I fell in love with faucets and shower fixtures by Phylrich. They are a local Southern California company and were great to work with. My style has marble and I was able to change the stone in my master bath to a pale onxy. Since they are manufactured in California, there might be a shorter lead time but who knows.

I got 2 Kraus faucets for my back to back sinks and they are awesome so far I have to admit probably a bit bought for look but we had a bit of an issue with one and Kraus was fast to send out the missing piece and a very nice customer service guy. IMO choose a faucet you really like ideally made in NA but sometimes a style is just not available made in NA I like Kraus for the same reason I like Ikea the price is good the product is well made with good german engineering and awesome customer service in my experience .BTW Kohler is also made in either China or India just like Kraus. IMO most faucets are made in China, India or Mexico,

I had my kitchen and 3 bathrooms renovated a few years ago. I chose a kitchen Kohler Koi faucet ( which had great reviews ) which I love); it has a powerful angled sweep spray, magnetic docking arm that swivels, and ceramic disc valves. For my bathrooms I chose Delta and Moen simple faucets. I am still quite happy with my choices, and all function well.
