looking for some advice regarding my first bike

my first post here thought the query flair fit my post best hope that's ok.

Im currently looking to buy my first bike and was hoping for some advice. i have around 3.5L budget.i prefer comfort over speed i like cruising around a 60-90kmph maybe an occasional 100-110. im around 184cm tall and weigh 78 kg and im looking for a big bike with a good road presence .ive rounded up my options down to 2 bikes the triumph scrambler 400x and the classic 350(dual abs version). ive test rode the triumph found it a bit hard to get used to because my only experience is with the hunter 350 but im sure ill get used to it . my main concerns and query for these bikes are

triumph scrambler

*does it have big gap in mileage im fine with loosing about 3-5kms per litter but any more might be an issue

*the first service is quite far off the dealership claimed it as a cost effective measure but isnt frequent services necessary to keep the bike in good condition.

classic 350

*is the higher torque of the triumph something ill frequently miss going the speeds i mentioned

so yeah looking for some advice on the following.please kindly also advice me on beginner maintenance and must have improvements
