Sometimes it depends how to use them as some of those weapons tend to have a somewhat slow turning rate. UEF forces have some of the best weapons ranging from machine guns and direct-fire gauss shells to antimatter artillery shells. The only exception to this is that the UEF have, as said before, the hardest armor of any faction. They have good units in all areas, but tend not to excel in one area or at one special thing (Such as Cybran's Hoplites and Stealth combo). The UEF tends to be the jack of all trades, master of none. Their T1 Tank: Striker is more arguable, however it does have 300 HP, as much as 50% higher than others. The T1 mobile light artillery: Lobo can also easily be said to be the strongest T1 artillery.
In Forged Alliance it is said that UEF have the strongest Tech 1 units, and from the stats it's obvious to see the light assault bot: Mech Marine is superior.
The same is true of nearly every other category of unit. The UEF ACU has 12000 HP, while the Seraphim ACU has 11500 HP, the Aeon ACU has 11000 HP, and the Cybran ACU has 10000. UEF units often have more HP, an attribute which makes them hardier than unit equivalents of other factions.
