Hi Yashbhatt
welcome back ... wow 11 months since we last heard from you ... hope you have been doing well

this a really small table top unit about a 4" mirror (115mm) ... wouldn't be my first recommendation, you are likely to outgrow it very fast
this one has the same mirror size as the first one ... so you are not gaining anything optically. The equatorial mount would take some getting used to
this one also has the same mirror size as the first one ... so you are not gaining anything optically.
advantages
1) shorter tube - easier to pack for travel
2) mounting can be use in equatorial or Al-Az modes

8" mirror, Dobsonian mount
would really be my recommendations to you. but they may be out of your price range ??
The thing is spending money on one of those little 4.5" scopes, you may well find you out grow it really fast
and you would have been better off putting that money you spent towards something a little bigger for a start
a 6" mirror scope is still a reasonably small scope
a 8" scope is the most common average sized scope for the majority of people
its a smaller number of real enthusiasts that go for larger scopes 10" and uphow's that help you ?
