Please define conservative. It may mean something different to us than it means to you.
Not by a huge margin - I think Leadsom could have been a good Prime Minister for the UK. I was delighted when the choice came down to Gove, Leadsom, and May because any one of them would - to me - have been a good choice (although Gove's recent treatment of Boris Johnson has annoyed me). But I think May is the better choice.
She is the longest serving Home Secretary in over a century and she has done a very credible job in that role. She's been less successful than I wish she had been on immigration, but that's also been a very hard thing to deal with and I hope will be easier now.
