If you have a chance in getting the top guardian ghost, you should definitely go for it! :)

Once you get that 1st 5*, things get alot easier. My first 5* (Lu Bu)  helped me get my second (Sasuke [HW]) and third (Benafa). I did have to spam some SW but well those were free so it was okay~ I only brought this up because the top guardian ghost has similar stats to Lu Bu. I'm guessing you'll have a similar experience to mine if you get it. Well the choice is up to you. ;)

Good luck and I think the most important part is to have fun :D
