Really satisfied with nexus 5 performance on marshmallow. Good work google and lg.
Its a pleasent surprise to see 2yr old hardware still strong enough to run the latest and heavy android os without a gltich. There are minor bugs here and there but its just software and can be fixed with a update. Inshort very satisfied and love my nexus 5 even more now. Marshmallow is perfectly stable with no memory management issues .go for it
