Honestly, if you are just getting a torque wrench for spark plugs (and any other BASIC projects at home) any brand will do. Just make sure it has the torque range you need.
I recommend “click type” because they are easy to operate correctly, and easy to take care of. Seriously, read the manual that comes with it, and follow the steps everytime. If you do this, it will last you a long time.
I bought my two torque wrenches from Harbor Freight for about $10 each. Torquing frame bolts or spark plugs? No problem. Would I use them for valve train or engine internals? Absolutely not.
If you don’t want to go the cheap route, go to any big box store like Home Depot or Lowe’s (US) and anything name brand will do, as long as it has the torque range you need.
OW2 is OW1. They just added a couple maps, removed some maps, took away a tank, and filled it full of grind and micro transactions. Absolutely no reason for “2”.
