You're right! The Strike Team and Breacher Team have different helmets, backpacks, shoulder pads, and (most importantly) weapons. Though, both units have access to the same add-on wargear: Markerlights, Support Turrets, Tactical Drones, and Guardian Drones.

It depends on the tactical role you want the unit to fill.
Strike Teams are all about range and synergy. They are best used at long range (up to 30") as objective holders, or at medium range (usually around 15") as anti-light infantry units. At medium range Strike Teams are also great when buffed by a Cadre Fireblade.
Breacher Teams are Tau close quarters units. Not close combat, but close quarters
- Breachers thrive at point-blank range, usually 5" away from their enemies (or less!). Breachers are only viable when very close to enemy elite infantry, so they usually need some way to get there- usually Devilfish Transports.
In short, Strike Teams are long-range anti-infantry units, while Breacher Teams are short-ranged anti-elite units that work best when mechanized.
Since you have the Start Collecting kit, a Strike Team will be more useful. However, if you plan to buy a Devilfish Transport, then Breachers may also be a viable choice.
