1.79 for Leverkusen to win is great I think. Leverkusen won in their last three head-to-heads. I don't see any reason not to see another win by them here. 
Xabi Alonso has started this season well too. First a German Super Cup won despite being one man down. Later a start with a win in the Bundesliga... I expect this winning streak to continue on this week as well. Both teams to score and over 2.5 goals could also be nice options (even over 3.5 goals would be logical).

They can't keep winning forever and it's expected that the Leipzig will steal some points eventually.
And it shouldn't be overlooked that Lepzig is a very solid and consistent team. They've been finishing in the top 4 (Champions League places) for the last six years in a row. This should be accounted for.
If Bayer is to lose points this season, it would be to teams like this one. Personally I wouldn't be betting on this game.
Home advantage should work in favour of Bayer though, as Leipzig tended to perform better at home than in away games.
But you can not look away from the head to head statistics since it points out to the performance of the team when ever they meet, Bayer Leverkusen has a better record when you work with the head to head and going with their previous season they still maintain the winning mentality even till this moment so hosting Lepzig at home wouldn't be an easy game since Lepzig has been consistent in the league for a long time but their consistency wouldn't stop Bayer Leverkusen from getting all 3 points in you consider their home record.
You already pointed at the home advantage which plays a vital role in motivating a good team to win matches and going with the performance of Bayer Leverkusen team, I doubt if they will share points with any team this season in front of their fans.
