wtffuck free version is uselss, and lowerping makes you lose packets since their servers are saturated.
But overall it depends where you live. If you are from Oceania regions, (New Guinea, Singapore, Philip.. etc,) your routing is generally horrible.. In this situation, what the lowerping/wtffast does, it tunnels your internet via their own servers that have stradegic peering, thus changes your peering route and perheaps shortens the distance from your home to the target location. So instead of your ISP choosing to put you via saturated route A through australia to the france as they detect where you are connecting, wtffast/lowerping in the other hand have server in singapore and this datacenter may take Route B instead along with your connection.
If you are in western world, EU/USA the amount of benefit you may gain is from 2 to 15 ms (Generally under 5) since all providers in these areas are Multi-homed at least via 2 or more cabels, while your local ISP in Papua New Guinea might be relient on only 1 or 2 routes initially. For reference, check network tiers and peering.
TL:DR If youre from third world country or from ASIA/South America with bad peering to world, it usually does help assuming that the tunneling provider can meet his end by offering alternative (and faster) routes for the data to connect. (i.e. making your connection to go via israel than saturated egypt link as you connect to europe.)
