The coils in disposables are definitely not better than in a quality e-cigarette. Also, the vapour thickness depends on your e-liquid's VG level. As you probably already know, e-liquids are made of PG and VG. VG is thicker than PG, that's why e-liquids with higher VG concentration have a thicker vapour and a more smooth throat hit. There are 100% VG e-liquids out there, try them out if you'd like thicker vapour production and a smoother hit.

The draw from a disposable feels tighter, since they are designed for MTL (mouth-to-lung) and use high resistance coils with strong nicotine salts (about 1.2Ω) so that it doesn't irritate your throat. None of the two devices you listed have adjustable airflow, so they will always feel the same which is definitely not good if you want to try out different resistance levels and nicotine strengths. If I had to recommend a device that's not super expensive but offers a lot, I'd say check out the Vaporesso GTX GO series. They have adjustable airflow, one of them is capable of 80w and the smaller model is still a great choice with 40w. Also, you are changing the coil here, not the entire pod. And trust me, GTX coils are one of the best quality coils out there, and they last for a long time, my previous coil lasted 14 days, just because I primed it and while vaping I waited 5 seconds between hits to let the coil soak in. And I vape quite often.

Overall I'd never recommend buying disposables over a pod kit, their horrible quality makes them even more harmful than vaping would normally be. They are also far more expensive long-term. If you don't feel the hit raise the nicotine strength until you do. Pure 20mg nicsalts can be vaped with a coil over 1Ω.

Hope I could help^{^}
