From what I recall there are only 2-3 manufacturers of traditional automotive shocks. All the different brand names are simply different marketing angles.
This is a widely discussed & misunderstood concept - regardless of how many manufacturers there are, the products that they sell are not necessarily interchangeable, unless they are sold as OE replacements, which are generally the least expensive of the line, and designed to meet the vehicle manufacturer's original equipment (OE) specification, for use with OE springs.
Old Man Emu (OME) shocks (and struts) are built (by Tenneco I believe) to OME specifications, which, on the shocks (and struts) marketed for Suzukis are distinctly different to the Suzuki OE spec..
It IS possible to pick up an application guide and select shocks based on end fittings and open & closed lengths, but you'll never see any details on damping rates mentioned - those rates, which are determined by the valving, are what differentiates between a ride that is merely firm, or one that is bone jarring - heavier vehicles require more restrictive valving, and that same shock, used on a lighter vehicle, will give a very rough ride.
Shocks (or struts) intended for off road use require different valving to those intended for on road use, especially if the vehicle is going to be used both on & off road - shocks on an on road vehicle will typically see low piston speeds, which requires more restrictive valving, the same vehicle & shock when used off road will encounter higher piston speeds, which require less restrictive damping - shocks for on road use will typically have fewer stages of damping, off road will have more.
Apart from the valving, there are the issues of construction - wall thickness (off road shocks typically have thicker walls), piston rod diameter (off road shocks typically have larger piston rods), piston diameter, monotube vs twintube (each has it's advantages & disadvantages), high pressure nitrogen, low pressure nitrogen, and the list goes on.
In short - unless you want to become a suspension engineer and figure these details out for yourself, either make sure that person whose advice you're taking, knows their stuff, or buy a package engineered to work together.
I understand that budgets are a necessary fact of life, we're all looking for the best "bang for our buck", but to suggest that because a Gabriel shock is manufactured by the same company as an OME shock, it will be of the same construction quality or suitability for purpose is just misleading.
Before I go, I want to share a comment I came across on another forum this morning ...
There's a big reason why people complain about the cost of OME suspension all the time. It's because they know what it can do for them, and it's what they want, but can't quite afford...
