Tigris has fallen off grace long time ago and by todays standards isn't considered a good weapon .
Redeemer prime requires very specific build and is quite decent but I wouldn't relay on it for Steel Path .
Soma prime is only half ( well kind of more then half ) decent if you have incarnon form unlocked for it .
Battacor is just regular Star Chart and nothing more , even if you have a riven for it .
Then it comes to Steel Path and Nemesis it boils down mostly to mod set up and some specific weapons if you want cheese it , for example a stealth Warframe will be always a good pick if you want to avoid getting shot sense invisibility scales infinitely .
Of course taking with specific frames is also a solid choice , both Rhino and Chroma can hold their line with the right builds as well as provide with damage buffs , as for weapons , if you want something cheesy go for Glaive Prime detonation , Incarnon Torid and Kuva Nukor .
Here some builds as example :
Note that Venka Prime here is strictly for Ash build as its passive grants higher melee combo ceiling that affects Ash Blade Storm damage
Shield conversion to armor is for the sake of boosting Iron Skin
Torid with Incarnon addapter
Glaive build specifically for manual detonation mechanic
