OK now I am confused. So you are saying the cheaper & smaller B&M units are the most efficient / best designed of the 3?
PWR
PWR’s Patented dimpled design universal plate and fin Transmission oil coolers are made of a full Aluminium construction that allows the cooler to be lightweight, compact and rigid while offering a high heat transfer and corrosion resistance. The patented dimple plates re-direct the oil flow, and in conjunction with the unique louvered fin design provide highly efficient cooling with low-pressure drop. PWR plate and fin transmission coolers are manufactured in 19mm core size for transmission, power steering and differential cooling for race and road applications as well as small engine cooling. Standard product range fittings include 3/8", 5/16" hose barb and dash 6 AN screw fittings, however PWR’s flexible manufacturing facility can offer custom fittings for specific applications on batch volumes as well as brazed thermo switch connections for fan operation.

The Hydra-Cool® transmission oil cooler is an effective & economical way to keep the transmission at its optimum operating temperature. High efficiency turbulators in each tube direct the fluid for superior heat transfer. Hydra-Cool's® unique plate & fin design allows for effective cooling, yet requires 33% less space. The Hydra-Cool's® compact design is perfect for applications where available mounting space is limited.
B&M
* Stacked Plate design
* ‘Low Pressure Drop’ feature
* All aluminum construction
* Oven brazed construction
* Small & efficient design
* Includes installation kit
* 3/4” thinline coolers are ideal for tight fit locations
* 3/8” extended nipple fittings providing improved hose & clamp contact
B&M SuperCoolers are 100% aluminum construction and use stamped plates sandwiched together to create one of the most efficient oil cooling devices available. Not only does this unique design provide for maximized cooling through more efficient heat dissipation but it also provides a much sturdier cooler which is practically impervious to flying rocks or other debris. The Super-Coolers intended for automatic transmission fluid also offer an additional feature known as “Low Pressure Drop”. The coolers assembled with hose barb ends include a unique bypass feature allowing a controlled amount of ATF to bypass the stacked plate core when the fluid is cold. This is beneficial in cold climate areas to guard against lube system failure. Controlled by viscosity, fluid is returned directly to the lube circuit through bypass openings in the stacked plate core. As the temperature increases, more ATF is directed through the core. This highly efficient design combines improved protection against lube system failure with the required levels of optimal heat transfer.
