Residential Solar Tech?

I’m considering bids from a couple companies near Annapolis in Maryland.

One of the tech discriminators between the offers is micro inverters vs. power optimizers. My research shows conflicting info on which is more efficient and reliable. Does anyone familiar have a perspective that isn’t readily available in the interwebs? I think I’m only concerned about total system efficiency (assuming same nameplate wattage) and I already know that I’ll have minimum shading impacts.

Both are offering 100% flashing on roof penetrations, backed by 20-25 yr warrantees on their work.

The quote with power converters is ~17% less - what am I missing other than a much more aggressive bid?
