Neither ENIG nor HASL is universally better. ENIG is usually the stronger choice when a design needs a very flat soldering surface, such as fine-pitch SMT or small-pitch BGA and QFN pads. HASL is often the more economical choice for designs with less demanding coplanarity requirements and can provide good solderability when specified and processed correctly.
