I know this thread is over a month old but I thought I'd answer anyway just in case anyone else is reading this down the track and is interested in LC HPT's as well.

Yes the 10miu is definitely more sensitive than say a 25miu so it will detect a pregnancy earlier for sure. When I was pregnant with DS2, I used a LC HPT at 9dpo and after the 10 minute mark I got what I thought was an evap line (a VERY faint line that appeared after 10 mins). The next day, I did another one, and got another very faint (but slightly darker) line around 10 mins. So I did another one later that day (because I'm a POAS addict ) and got another faint line but this time before 10 mins was up.

So by the following day (11dpo) the line was appearing slightly darker and before 10 mins. So the original "evap line" really was an early BFP. I know they say 9dpo is too early for a BFP - maybe my O date was a day or 2 earlier (which is possible and does make a bit of sense when I take into account other factors), but still, it showed me a faint BFP very early.

I did find however, that the actual lines themselves were fainter and took a bit longer to appear than the Discover and First Response Brands. But it definitely picked things up early.

First Response still remains my favourite HPT though, although its more expensive than the LC HPT's
