The Thermal Grenade is the first turret unlocked that has the ability to deal damage to multiple ground units, making it very useful in early stages. The Thermal Grenade excels in wiping out hordes of oncoming weaker droids, such as the B1 Battle Droid. Although this ability is useful, the Thermal Grenade has one of the lowest attack stats of all turrets in the game and you fill find that it loses its effectiveness against any enemy droid more powerful than the B1 Commander Droid. Placing them in large, close, groups most of the times compensates for this however.
It is suggested in-game to replace Thermal Grenades with Mortar Cannons. They both have the ability to damage multiple units with one shot, however, the Mortar Cannon boasts far better attack power and range. Although the Mortar Cannon is an arguably more popular choice, it does not outperform the Thermal Grenade in all areas. The Thermal Grenade has a much faster firing rate, compared the Mortar Cannon's relatively slow firing rate, and is cheaper and, therefore, easier to upgrade.
The Thermal Grenade loses its main downside of boasting low attack power when in its upgraded forms, and when this is combined with its faster firing rate, you will find that it can take out large groups of even moderately strong droids with greater efficiency than the Mortar Cannon.
