i see ur lex is around 20... it onlt really starts getting good after that
most weapons can be good but it depends alot on what mods you have and what level they are
multi shot mods are all rare but super good once leveled (i still need need shotgun and rifle myself) also i find its better to have a few leveled dmg mods than alot of diffent ones (basicly since they take up more mod points to equip than to level one already equiped... this being said mods like seration get vary coastly to level after awhile they are worth it but within reason

weapons depend alot on playstyle

lex and akbolto are great sidearms... krakan is fun but honestly once leveled the other two are better, theres nothing wronge with strun tho numberswise atleast hek is better (just takes longest to get of any weapon atm i didnt care for paris my self take too long to level gorgon is graet if you want a ast firing wep with large mags, latron is good after u get it around level 12+ boltor about same for melee i love gram but any heavy wep is great from what i have seen (wondering about that new glave wep tho

Which heavy weapon should I get?

Gram, Scindo, Frago or the new heavy pole?

My chuck norris setup is:
Volt - incredible AoE, capeble clearing whole room in seconds
Boltor - tearing everything in close-mid range
Lex - 1shot kill snipe pistol
Amphis - armor ignore, long reach, hits multiple targets, jumpattack stunning instead of knockdown so no stupid stuck-in-chopchop-knocked-enemy-animation
Sentinel - guardian card prety much covers your survivability with any warframe (along with warframes shield cap card)
