webmod is retarded...
phprcon is limited by what you can get from the built in network protocol (queries from outside the game). webmod is a mm plugin meaning it can get ANY data the game has to offer such as:
Player Frags
Player Deaths
Player Health
Player Armor
Player Weapon Held
Player Model or Class
Players Team
Team Scores
Team Names
Entity info (think sentry guns or flags in TFC or bombs/VIP in CS or capture points in DoD)
In otherwords, webmod is retarded...
