The major concern with Trifexis is that it containes spinosad (comfortis). Some of us really don't like it. If your pup is doing well on Comfortis and you are set on it, then there is no reason to avoid Trifexis. However, the heartworm preventative is not equivalent to Heartgard. It's equivalent to Interceptor.
I see no problem giving an all in one pill.
