Your visual impressions aside, the wrenches are very good in practice. Look for the data from Torque Test Channel, for example (for Facom, I don't think they tested V-series specifically).
Price compare those V-Series wrenches against Facom offerings too. I bought the metric reversible ratcheting set when it was on special awhile back. It skips some sizes and I thought: "Hey, I'll grab the missing ones from Facom and still be cheaper than a full Facom set". While that's true, I realized that the 3 missing sizes were going to cost more than my 8pc set and changed my mind.
The hex bit sockets and t-handles use Mac RBRT technology - well, more like 1/2 RBRT. Still, compare the set versus an RBRT and it's a nice budget offering (or as pointed out in a recent thread, now Dewalt is offering V-series lookalikes for even less - lots of SBD crossbreeding going on).
Basically, V-series is a selection of Facom tools with different branding. They're quite good and apparently good value too. Kind of a weird offshoot of the Craftsman brand - I wondered when they first came out if they were an experiment. I thought maybe SBD wanted to see if premium tools would sell under the Craftsman brand too - but without having to manufacture something new. They stuck around longer than I expected though.
Overdrive also looks good - but I think it's an entirely different category. It seems like SBD is trying Mac and Proto RBRT and Anti-slip designs in tools designed to compete in the mid and lower-tier price points. That's a great idea honestly - though I wonder whether it might cannibalize their own sales.
I don't think there's been any testing on these yet. "Cheap" tools have improved so much in the last decade, that the gap between cheap and expensive has shrunk. That doesn't mean it doesn't exist, but even cheap import tools can be relatively precise, have good chrome and be made of good materials.
If the OverDrive tools use Anti-Slip Design similar to Proto, might they end up offering 95% of the performance for a fraction of the price? One can hope.
