Both Specific port and Wildcard VS on the same VIP

I need help to understand what is the best practice in the following scenario. I have the following VS

s : 

FTP (port 21)
SFTP (port 22)
SFTP implicit ( port 990) 

Because explicit FTPs (TLS)  also was needed I had to build a wildcard VS (all ports) . 

I understand that if a specific port is VS exists the traffic will be processed by that VS and it defaults to the wildcard. 
On the technical side everything seems to be working fine , however I

m wondering about the best practice , which brings me to the following questions :

Should I leave port specific VS`s in place or delete them and let the traffic be processed by the wildcard VS.

Thanks, Adrian
