Some advice on tyre size please.

My Raleigh MTB originally came with, if I remember correctly, tyres 26 x 1.9. Many years ago I replaced them with a pair of Raleigh branded tyres in size 26 x 1.75 which have served me well and I’ve been happy with.
I am now considering buying a pair of Schwalbe Marathon Plus tyres and I am wondering if I might benefit from a narrower tyre and buy 26 x 1.5 ?
I predominately ride on tarmac roads so I‘m thinking a narrower tyre would be less ‘draggy’ on tarmac. The actual difference in width is only a quarter of an inch or 6.35 millimetres.
My question to you experts out there ….. is the minimal difference in size worth bothering with ? Would I roll along a bit quicker on a slightly narrower tyre or would I not notice the small difference ?
The rims are made by Alesa and have written on them 26 x1.75 so perhaps a narrower tyre is not compatible anyway ?
Thanks in advance, all suggestions welcome.
 
At the same pressure, wider tyres have lower rolling resistance M+ tyres have notoriously high rolling resistance due to stiff sidewalls, I would advise wider size.
Thinner tyres have lower weight and air resistance. For flatland easy riding these are not so significant.

If you don’t want draggy, Marathon Plus aren’t a great choice unless puncture protection is your primary concern

You can certainly buy lighter faster tyres but none so puncture resistant than M+. Depends what your priorities are.
There are a few options in 26 X 1.5 slicks.

Thanks to all of you above for the info. I would add that puncture resistance is indeed my number one priority when weighed against the other factors and that is why I thought Marathon Plus would be a wise choice.
I have Marathon Plus 27 x 1.25 on my two older Claud Butler bikes and whilst I have picked up the occasional puncture over the years I think they have stood up pretty well.
I will have a look at the Marathon Supremes and see what they offer ( thank you Mo1959 )
From the advice given I’m sure I will stick with the 1.75 width and abandon thoughts of going down to 1.5
I have checked out the prices on Spa Cycles website and also SJS Cycles, SJS come out best with the lowest price at the moment.
