Need some help

Guys, I'm a new subtank user. I used sigelei mini 30w + subtank mini, using 0.5 occ. And my friend using rdna40 + subtank (the bigger one), using 0.5 occ. Both fire on 25 watts, and at the same volt. Now the questions : why the Rdna tastes so much better on the flavor than my sigelei? Is it because the devices or the subtank? Even if I run my sigelei on 30w and higher volt, I still can't match up with rdna flavor. Flavor on mine is bland, inhale I don't taste anything, I do taste a thin flavor on the exhale. Rdna is full on both. and if the devices do make a difference, how can I perform my subtank to that level? Maybe using a lover ohms build? Cos my sigelei can take it to maybe 3 ohms. I do think rdna has an overhead wattage, cos I heard ipv have to take it to 60 watts to outperform 25 watts rdna. So how to make my vape better? Because personally I don't want to replace my sigelei, I'm in love with the design and else. Rdna is okay, but it's way over my budget.
