, Hello Emillo and welcome , The Vixen would be the better scope if ,,,,, here comes the 'But' there is always a but ,,,, the Celestron comes as a whole package , eg. , mount included so you will be using it almost straight away , the Vixen is (?) OTA only ? at that price you will need a mount , eyepieces etc. so if I am right here about the Vixen being OTA only I personally would say grab the Celestron 130 and learn from it as it will show you nice views for years .
The Vixen is a very good scope but if it has no mount you need at least an EQ5 minimum , or better HEQ5 but these are $500-$1000 depending on model so you see it gets expensive very fast and at 15 years old that is probably to much , sorry to say .
Grab the 130 and enjoy it , these are good ( complete ) scopes . my 5c .
